I have a list of file names in a variable-length @dir_list array. I want to match each item in the array that has some suffix eg .zip, .log, whatever; then I'll have to do some operations on them. What is the most efficent way to do this, since I will be doing a great many of these?

I could do this, but is there a better way? 
my $suffix = ".zip"; # value is likely to change

foreach my $file (@dir_list) { 
   if ($file =~ /$suffix$/e) { 
       print "Match on $file!\n";
       do_this();
       do_that();
   }
}
