Before posting, I went thru the offical doc and some searching forum,
still hvn't found how to view the ruby core component source code.

For example, I'd like to know how the Enumerable implemented the
iterator, from the http://www.ruby-doc.org/core/, I can see following
files are involved:

enum.c
lib/set.rb
lib/soap/property.rb
ext/enumerator/enumerator.c

But how to check out the code above?

More things confusing me: For improving the performance, ruby builtin
all the core component in parser?

Thanks.
