00:07 <FromGitter> <iDev0urer> Ahh yeah, I'll see if I can put that in there

00:08 <FromGitter> <johnjansen> i dont know how heavily you leaned on the stdlib shaping up very well and already extensive, and that often very closely mirrors the ruby one

00:08 <FromGitter> <johnjansen> but not always

04:41 <FromGitter> <iDev0urer> @here is there a way to add a method to a built in literal? Or would that literal have to be extended as a new class? For instance, adding a `to_xml` method to the `Hash` class

04:41 HakanD___ has quit [Ping timeout: 250 seconds]

04:43 <FromGitter> <jwoertink> Can't you just reopen the Hash class and write a to_xml method?

04:44 <FromGitter> <iDev0urer> @jwoertink what do you mean by reopen?

04:45 <FromGitter> <jwoertink> ```class Hash ⏎ def to_xml ⏎ end ⏎ end``` [https://gitter.im/crystal-lang/crystal?at=580aeefa278cc54c6f5a3664]

04:46 <FromGitter> <iDev0urer> I was thinking that something like that might work, but I wasn't sure

04:46 snsei has joined #crystal-lang

04:46 <FromGitter> <jwoertink> I'm on mobile, but I'm pretty sure this works

04:47 <FromGitter> <iDev0urer> I'll try it out

11:38 <jokke> is it possible to define methods from a method missing hook?

11:44 <BlaXpirit> jokke, probably not

11:44 <jokke> :/

11:44 <BlaXpirit> think of it as pasting code in the place where it's called, not into the class

11:49 _whitelogger has joined #crystal-lang

11:51 <jokke> oh damn it

11:51 <jokke> i can't even make procs Proc(Object, Bool)

11:52 <jokke> or define that as a type

11:52 <jokke> i want to create an instance variable that is an array of procs that just compare two objects

15:12 <FromGitter> <ysbaddaden> yes, using Object as a type is known limitation that can't be lifted for the time being. There are plans for Object to be usable as a type, but don't expect it any day soon.

15:13 <FromGitter> <ysbaddaden> it hurts at first, but after a while it looks better to have more restricted types
