  2. Here are half a dozen ways to get that.

    The value of an answer is directly proportional to the care
    given in asking the question...


    -----------------------
    #!/usr/bin/perl
    use warnings;
    use strict;

    $_ = q($string['bababa']='jajaja');

    my @matches = /([abj]+)/g;
    print "@matches\n"; # only the "good" letters

    @matches = /'([^']+)'/g;
    print "@matches\n"; # single quoted

    @matches = /(\w+a)/g;
    print "@matches\n"; # ends with "a"

    @matches = /(\w+)'/g;
    print "@matches\n"; # ends with "'"

    print substr($_, 9, 6), ' ', substr($_, 19, 6), "\n"; # no regexes at all!

    tr/=/ /; # this one's *not* a regex
    s/[^abj ]+//g; # but part of this one is
    print "$_\n";
