It might not actually be the '$' just some mechanism for matching a
string that must end after some substring. Of course the ${ % } method
does just that, but if the test is from the beginning of the string it's
more involved. But Roman's method is so satisfactory that maybe it's a
thin point. It would seem to require some new special char that it
seems we don't have and that would bloat the syntax space. Besides,
Roman's method is more self-explaining anyway.
