If there's no variables inside to be interpolated, the optimizer transforms double quotes to single quotes: 
    #!/usr/bin/perl
    #testscript
    if($a eq "quackidiquack") {
    }

    if($a eq 'quackidiquack') {
    }

Now let's see what the optimizer does: 
    perl -MO=Deparse testscript
    if ($a eq 'quackidiquack') {
        ();
    }
    if ($a eq 'quackidiquack') {
        ();
    }
testscript syntax OK
