Dont use $&, it'll slow down ALL regexps even if you use it once!

Either
@matches = ($str =~ /(i[st])/g);
or
while ($str =~ /(i[st])/g) {
my $match = $1;
...
}

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain.
I can't find it.
