<_dave> does crystal do open classes where i can append a method to, say, Int32s?
<FromGitter> <naqvis> yes, you can
<_dave> nice. trying to figure out the way though.
<_dave> i'd search on the forum but it's being a pain in the butt.
<FromGitter> <naqvis> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=638b70e2fbde3846f199e276]
<_dave> ah. and i presume it has to be top-level to actually manipulate the core struct?
<FromGitter> <naqvis> yeah, you can *monkey patch* any class, as long as you keep the namespace and name in sync
<_dave> 👌

<_dave> oh thought i was just there. my b.

<FromGitter> <djberg96> Did a `sudo apt install crystal` on my Ubuntu system. Worked ok, but running `crystal i` results in "Crystal was compiled without interpreter support"
<FromGitter> <djberg96> Do I have to build from source?
