06:32 <Sankalp> What is the use of the `for` keyword in crystal?

06:47 <Elouin> there is a `for` keyword?

06:47 <FromGitter> <oprypin:matrix.org> sankalp: it is not a keyword. only a keyword in macros. a good syntax highlighting definition will only highlight it in macros https://github.com/pygments/pygments/blob/2f5722d2dc1290c9222452b87a47963e66698a8d/pygments/lexers/crystal.py#L353

06:48 <FromGitter> <oprypin:matrix.org> https://carc.in/#/r/dsrf no error see

06:48 <FromGitter> <oprypin:matrix.org> https://crystal-lang.org/reference/1.5/syntax_and_semantics/macros/#iteration

06:50 <Sankalp> Ahhh yes! It's used in macros

06:50 <Sankalp> I had totally forgotten about macros

06:51 <Sankalp> Thank you @oprypin!

17:01 <FromGitter> <azurelmao> Is there a size-restricted queue in crystal or do I have to make my own with Deque?

17:02 <FromGitter> <Blacksmoke16> restricted in what case, like when you add something new and it's full, last item drops off?

17:06 <FromGitter> <azurelmao> exactly that

17:13 <FromGitter> <Blacksmoke16> nothing built in like that afaik

18:38 <FromGitter> <RespiteSage> If you know the size at compile-time, it probably wouldn't be too hard to write a circular buffer using `StaticArray` under the hood.

18:39 <FromGitter> <Blacksmoke16> deque already implements a circular buffer

18:40 <FromGitter> <Blacksmoke16> but doesnt handle popping off extra values
