Hello, O wise ones. If I've understood my reading, the addition of the one-time-compile modifier, "//o" to my regexps saves time only if the pattern inside the regexp is a variable, e.g.: 

    $pattern = "something";
    if ($foo =~ /$pattern/o) { #stuff }

Is my understanding correct, or does the "o" still help with an actual *expression* inside, e.g.:

    if ($foo =~ /^dis_isa_pattern$/o) { # stuff }

Many thanks,
Deane
