Actually, what would be even more interesting would be a Ruby
interpreter written in Forth or Scheme, rather than in C or Java. :)

Seriously, though, a simple Forth can be built with indirect threaded
code and all that needs to be "bootstrapped" is the so-called "inner
interpreter". Traditionally, that's done in assembler for speed, but I
suppose a Ruby inner interpreter could be built.
