woozong 🅅yo yo <a href="https://post.lurk.org/tags/commonlisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commonlisp</a> peeps, I'm getting back into some cl hacking and I have a question: AFAICR when I did a (ql:quickload "some-library"), I could then, in later session just load my asdf package with the dependency to it, and it would use the "some-library" I ql-loaded in a previous session. For some reason that isn't working anymore. Did I forget some config somewhere? i.e. only quickload once and then have it available to asdf in later sessions. any ideas?

Vassil Nikolov | Васил НиколовIn this line of thought, a simple illustration that may be of interest.Part 1: Put these in a file and compile it:(defun wt () "Wrap a throw." (throw 'foo nil)) (defun bar () (loop repeat 3 do (print 'baz) (wt) finally (print 'quux)))There cannot be a warning about unreachable code and there indeed isn't.Part 2: Insert(declaim (inline wt))before the two definitions above. SBCL's file compiler does emit a warning now.<a href="https://ieji.de/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a><a href="https://mathstodon.xyz/@weekend_editor" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@weekend_editor</a> <a href="https://hachyderm.io/@davetenny" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@davetenny</a>

Nicolas MartyanoffI still love <a href="https://fosstodon.org/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a> but I spend too much time dealing with production issues in my life to ship production software in a language that cannot be statically typechecked. Yes, type declarations sometimes help with specific implementations; but "sometimes" is just not good enough.

Vassil Nikolov | Васил НиколовP.P.S.Yes, "upward go" is possible. (As _of course_ it should be.)So one is allowed, for example,(tagbody (loop repeat ... do ... (go end) finally ...) end)where this _isn't_ an endless loop, but the epilogue is unreachable nevertheless. Naturally, in the wild the `go' and `tagbody' forms will be in a macroexpansion.<a href="https://ieji.de/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a><a href="https://mathstodon.xyz/@weekend_editor" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@weekend_editor</a> <a href="https://hachyderm.io/@davetenny" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@davetenny</a>

I moved to <a href="https://fosstodon.org/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a> as my go-to language.

Vassil Nikolov | Васил НиколовYes. Embarrassingly, it took me a whole five minutes to notice that.Note that unreachability is detected in the macroexpansion. Emitting a meaningful error message would take a lot of work:either implement all of that analysis for `loop' as a special case _as well_or relate the pieces of the macroexpansion back to the pieces of the original form.Now, justify that effort...<a href="https://ieji.de/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a><a href="https://mathstodon.xyz/@weekend_editor" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@weekend_editor</a> <a href="https://hachyderm.io/@davetenny" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@davetenny</a>

It doesn't tell me why, that's generally an exercise for the author, and here I leave it for you to identify for your amusement. I liked this particular catch by the compiler.I am a huge fan of SBCL's compilation warnings. IMO it's one of the things that makes Common Lisp a much better production language than some other lisps.(Is there a way to hide spoilers in Mastodon posts?)

Andres Moreno<a href="https://merveilles.town/@aartaka" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@aartaka</a> Paul Graham (the power behind Hacker News) is a big proponent of <a href="https://hachyderm.io/tags/commonlisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commonlisp</a> A whole Lisp-oriented culture emerged on HN.While no longer as obvious as it was then, it is still with us.

Artyom BologovAt times I don't get the logic of <a href="https://merveilles.town/tags/HackerNews" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HackerNews</a>. My latest post (<a href="https://aartaka.me/customize-repl.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://aartaka.me/customize-repl.html</a>) hit 70+ points on HN, despite being quite niche and supposedly oriented towards <a href="https://merveilles.town/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a>. Why? But it's good to see at least some of my posts back on HN after two months of no one posting the stuff (I poured my heart into.)

They are the poor compiler writer's case or switch statements, of course.Now, Fortran also has (or had) arithmetic IF (a three-way branch on the sign of a real value).
