I bought the O'Reilly bash book a few days ago, and it mentioned something
about being able to write your own builtin functions as shared libs.
So, if is only for development purposes, you could do it that way and
presumably have full access to bash's internal data structures.
I can't give any more details because the book is in the office and I'm
not.
Later,
Kenn
