Yes: the ones I came up with last night were somewhat novel, too.

1) A security sandbox, for running untrusted scripts.

2) Introspection into other scripts -- if the interpreter has an
implementation in ruby, you can get at any part of the representation of
the script.

3) easy extension of the interpreter for testing, language development
and special uses.

4) to show off that it can be done.
