Historically, all languages eventually get written in themselves eventually.
C is pretty famous for (practically) bootstrapping itself this way.

It is an interesting exercise, and is a good way of finding problems
in the language.  In Ruby's case, I would think it would be ideal, since
Ruby is pseudo-code made real.

Caveat: I don't think anyone proposing to self-implement Ruby is expecting
that the resulting code would replace the C code, but that a Ruby
implementation of Ruby would facilitate creating interpreters in other
languages and help clarify some of the rules of Ruby.
