( #3333=superdoc: print w/replies, xml ) Need Help??
You beat me to it!! I had it the other way round though as per the OPs example. The joined @a is only calculated once and then matched against the regex made from joining @b with .*?
my @a= qw (a b c d e f); my @b= qw (a b c); my $joined_a = join '', @a; my $joined_b = join '.*?', @b; print "yes!\n" if $joined_a =~ /$joined_b/;

But I guess there are no prizes for coming second...
