   It was misinterpreting $) in patterns as a variable.  At patchlevel 27
   it's interpreted correctly as an end of line check and a terminating paren.
   Which means you can't interpolate $) into a pattern directly.

   $/ has never been a problem.

Well, what exactly are the rules for which variables can be used in
regexps and which can't?  That is, why is interpreting "$)" as e-o-l
and paren correct and interpreting it as a variable incorrect?

I guess I don't really need an answer here, but I hope that the book
will be enough of a language reference that all such questions will be
answered by it.
