Thanks for the report! I think this must be a Gatekeeper interaction that prevents "DrRacket.app" seeing adjacent files. When I try that installer (looks like it's from the Northwestern snapshot...

Sorry — I lost track of this one. I'm pretty sure the error is because Mac OS thinks the application needs to be sandboxed, and the sandbox prevents DrRacket from...

An obstacle to that change is that `procedure-reduce-arity` currently can be used to hide the structness of an applicable struct. I'm not sure I've ever used it that way, but...

> This doesn't matter for cases where `procedure-reduce-arity` isn't changing the function's arity, correct? I had indeed lost track of the original point. A `new?` argument where `#f` matters only...

The problem with `(ความกว้าง 500)` should be fixed by the `snip-lib` commit.

Sorry that I missed this, even with the ping. I like the idea of a way to set a head addition everywhere, but I think it still works better to...

... and maybe `head-extra` should have worked that way in the first place. Rechecking the documentation, I don't think it's clear on `css-addition`. It talks about lifting CSS additions up...
