Please describe the problem:
Syntax highlighting doesn't work properly for Perl 5.10 new logical defined-or operators, // and //=.

Steps to reproduce:
Test code:
#!/usr/bin/perl
$x = $y // $z;
...whatever...

Actual results:
It seems that the second slash is mistaken for a regex delimiter. The first slash is coloured as a bareword and the second slash as a delimiter, with everything after the second slash being coloured as an interpolating string, until another slash is found further down the code.

Expected results:
The // or //= should be coloured as operators, and whatever follows shouldn't be considered as a string.

Does this happen every time?
Yes.

Other information:
As a cheap workaround, one can add '#/' at the end of the line containing the offending Perl code. Gedit will not see the '#' and will consider the '/' as a regex delimiter, whereas perl will consider the '#' as a comment delimiter and thus won't see the '/'. The highlighting will still be wrong on this line, but at least it won't mess the rest of the code.
