The perlre states: "(the 'o' modifier) avoids expensive run-time recompilations, and is useful when the value you are interpolating won't change over the life of the script. However, mentioning /o constitutes a promise that you won't change the variables in the pattern. If you change them, Perl won't even notice."

So I wrote this: 

--------------------------
my $pattern = "homey";
my $value = "homeylovekins";
match();
$pattern = "wigwam";
match();

sub match {
    if ($value =~ /$pattern/o) {
        print "yes";
    } else { print "no"; }
}
-------------------------------------

But still got this: yesno

What am I missing? Shouldn't the pattern match string remain "homey" for the duration of the script per the perldoc? Thanks, Monks.
