I think you've got the behavior of munch backwards.  It will eat any
characters that _are_ in the pattern string.  Since 'b' is not in the
string "-", it returns immediately, since it didn't munch anything.

If you're looking for something to split up a string into tokens, you
could either use find or split; the former could be used to slice the
string one piece at a time, and the latter does it all at once at the
expense of allocating a new array to put the slices in.

Sorry, it seems I ferked up a bit there, yes (I did not in the code
in which I intended to use it). And yes, I certainly could use split,
I just wanted to use munch.

Example of what I wanted:

munch("1 + 3", "0123456789+-*")`;

I managed to fix it, though. Just put '-' as the first character of the  
string.
