I'm not really comfortable with regular expressions, so I wasn't
going to suggest this anyway.  :)   As for nesting, we could
simply count the number of { } and << >> to figure out when the
expression is over.

My solutions often end up quite hack-ish, but they work.  As long
as a human can explain to me what they want done, I can get the
result... or in this case, I can teach somebody how to do it
themselves.

The first step would be simply to get a working program that does
this, with no attempt being made to integrate it with convert-ly.
Once we had working code, we'd investigate merging it or simply
leaving it as a standalone tool for that particular conversion.

Besides, these's nothing wrong -- and quite a few things right --
about inexperienced programmers rewriting code.  :)
