Right, as in:

  my $foo = qr!allan$!;

TextMate thinks that it's the variable $! instead of end-of-line followed by regexp delimiter.  That's what I meant by the variable pattern having precedence.

It's not ambiguous.  The end delimiter is the first non-escaped character that matches the start delimiter.  Perl finds the end delimiter and then realizes that the $ must be an end-of-line marker.  When using slashes as the delimiter, you have to write $/ as $\/.

In this case the variable pattern doesn't know that $/ isn't a valid variable name.  Do we have to recreate the variable pattern instead of importing it?
