Perl syntax highlight is broken

[Sco768]

Issue Type: Bug

Perl syntax highlight breaks with a simple line involving two pairs of square brackets:

    use strict;
    my %FORM = (logins => "Aaaa, Bbbb Cccc");
    my $good_highlight = "a string";
    # everything after this line is highlighted the wrong way
    my $logins_from_form = [split /[,\s]+/, $FORM{logins}];
    my $bad_highlight = "a string";

1. Create a new .pl file or choose Perl language manually, edit the file
2. Put the code above
3. Notice that the colors in the last line are different from the third one. In a real life situation that would make a few screens of mostly brown (or whatever "my" is in the last line) lines until a similar line would fix the highlight back.
