And, to avoid looping through all the regexes, it's possible to combine the individual regexes into a single regex (probably a big performance win if there are many regexes): 
>perl -wMstrict -le
"my @regexes = (
   qr{ foo }xms,  qr{ bar }xms,  qr{ baz }xms,
   );
 my $any_regex = qr{ @{[ join '|', @regexes ]} }xms;
 for my $file (@ARGV) {
   print $file, $file =~ $any_regex ? ' MATCHES' : ' no match';
   }
"  xfooy  snork  bar
xfooy MATCHES
snork no match
bar MATCHES

Remember, however, that Perl's  | (vertical bar) regex alternation operator provides ordered alternation: the overall alternation will match with whatever sub-pattern first matches in the alternation sequence, regardless of length. See Matching this or that in perlretut.
