no idea how it got to this ( working fine yesterday ), but right now,
opening the following simple script in perl-mode leads to it incorrectly
identifying a paren mismatch ( marked by <- HERE in the code ).
This pretty much renders perl-mode unusable as I cannot
even use hashes anymore. I have no idea of lisp ( shame on me ), but
would prefer to continue using emacs and the perl-mode, since I am no
fan of fancy colors all over ('cperl-mode'), so I would be most thankful 
for a fix.
PS: the bug appears even without the comments :P

code:

#!/usr/bin/perl
my $hash = { x => 1, y => 2 };# <- Here, the '}' closing bracket is 
reported as mismatch
# not fun, since now all code coming after this is no longer parsed 
properly

print "hash: ".$hash->{x}.", ".$hash->{y}."\n";

Thanks for the report; but, by experiment, this was fixed in Emacs 24.1.
So please upgrade (current is 24.3).
