Well blokhead already posted what's probably the best answer, and the one that I wanted to give, but I've got to post something. So here:

if ($String =~ join('|',map($_ x 5, qw(A B C D E)))) {}

Admittedly it takes 3-4 times as long according to benchmark... but it was so much more fun to write ;p.
