in reply to Replace $a with $b if $a ne $b

Doesn't this do that directly? $a = $b; The conditional seems unnecessary since it has no effect.

    Take this values of $a and $b: 

    $a = 12;
$b = 2;

    From his words:

    if $a does not match $b

    I assume he wouldn't want to put the 2 in $a, as $a already matches $b.
