Too bad regex's don't take @var to mean "any of those". So I wrote: 
my $goodnames= join ('|', map { quotemeta} (@names));  # do that once

# later...
s/stuff (?:$goodnames) stuff/o  # each time I need that

To improve upon this, what's a good idiom for doing the equivilent of: 
my $goodnames= join ('|', map { quotemeta} (@names));
$goodnames= qr/$goodnames/;

in one statement?
