Just a thought...the following would be *really* cool:
my $pi = Pi::Generate;
# Check the first 200 characters only; halt w/success if NO match
print "There's a letter in here!\n" if ($pi =~ /[a-z]/h200t);
# Check the first 200 characters only; halt w/failure if NO match
print "There's a letter in here!\n" if ($pi =~ /[a-z]/h200f);
This would be useful for cases where you might be dealing with
infinite data, or when you are only going to need to use the first section
of a string.
