Why aren’t question marks allowed in variable names in Julia? This question has probably been discussed elsewhere so perhaps someone can point me there if they know the location. Its a small thing, but it would be nice to write scheme style predicates if possible (eg. integer?(x) instead of isinteg…

This works though help?> a′ "a′" can be typed by a\prime<tab>

ok! that’s great. clearly i need to go read something in the julia documentation. now I just have to figure out how to type that character into emacs :slight_smile: edit: ctrl-x 8 RETURN prime meta-x describe-char

The same key binding should work in julia-mode in emacs.

and so they do! that’s very nice.

While we are on the subject, it would be really nice if ᵀ and † were special characters reserved for transpose and adjoint, respectively (is there a superscript dagger? I couldn’t find it). I’ve made some ill-conceived suggestions about unicode before, but I feel pretty confident that this one is…

Opened an issue about this here .

The more I think about ? the more I think it’s a good idea. The possibility of having ugly expressions like isthistrue? ? :yes : :no makes me a bit uncomfortable, but at least in the most common usage ? would only appear in function names (if everyone behaves themselves). One further qualifying co…

Yeah ¿ (\textquestiondown) is a decent substitute, with the caveat that it takes a lot longer to type.

This is a common naming pattern in Ruby, used to designate Bool values. This would make prepending is to function names unnecessary. Thus, functions like isempty would become empty? which would pair nicely with existing empty!. x |> empty? && do_stuff() would be very nice. But I find that empty?(x…
