Faster way to do a regexp using a hash

[sftriman]

I've been wondering for a long time... is there a slick (and hopefully
fast!) way
to do this?

foreach (keys %fixhash) {
    $x=~s/\b$_\b/$fixhash{$_}/gi;
}

So if

$x="this could be so cool"

and

$fixhash{"could"}="would";
$fixhash{"COOL"}="awesome";
$fixhash{"beso"}="nope";
$fixhash{"his"}="impossible";

then it would end up

"this would be so awesome"

Thanks!
David
