17:52 <jokke> jhass: remember when you advised me against using yield arguments in macros (you said it's more a bug than a feature)? What did you recommend instead?

17:53 <jhass> nothing I think

17:53 <jokke> hm

17:54 <jokke> jhass: i'm trying to write me a handler which has an "on foo" macro. it takes a block which will be the body of a "handle_{{foo}}" method. I need to pass some info to that method though.

17:57 <jokke> as in: on :foo do |message| ... end

17:57 <jhass> #1338 hf

17:57 <DeBot> https://github.com/manastech/crystal/issues/1338 (Unclear semantics in macro yield)

17:58 <jokke> mmh yeah

17:59 <jokke> blocks loose access to the scope they're defined in as soon as they're captured, right?

17:59 <jokke> *lose

18:04 <jokke> jhass: ^

18:07 <thor77> ah, thx

18:07 <thor77> :)

18:07 <jhass> jokke: no, captured blocks still closure

18:07 <thor77> .length was valid before

18:07 <jhass> yeah, got dropped in favor of .size

18:08 <rmosolgo> mm, i'm just learning crystal and i love that all the data types respond to #size (and only #size?)

18:08 <jhass> only size by now, yes

18:09 <BlaXpirit> jhass, read at the end #557 , do you think this is normal?
