If you know a bit of C, it's pretty interesting to read the ruby
sources from time to time. They're very readble, and it's the
definitive documentation after all ;-)
The code for let say Array or Integer etc. is pretty easy (maybe some
details are tough). You'll get the picture how the things are working
on the inner side.

There's even guide how to read them (in what order) ;-)
