in reply to Passing results of a substitution to a function

You could always use grep. Note that I changed the print() in blah() to a return, otherwise you'll end up printing an extra value out.:

my $word = 'BLAHBLAH';
print blah(grep{s/BLAH/COW/}$word);

sub blah {
  my $stuff = shift;
  return "$stuff\n";
}

    This seems to work quite nicely - but needs a small amount of tweaking to make sure grep doesn't return stuff in scalar context.

    Ok - I now have something which works a lot more niftily: 
    my $word = 'BLAHBLAH'
blah(grep {s/BLAH/COW/ || 1 } $word);

    The { s/BLAH/COW/ || 1 } bit is required as I want to also pass in arguments which do not contain 'BLAH' (which grep would usually.. er.. grep away ;) ). I was worried about list context before because I was trying to get around this by using 
    blah(grep(s/BLAH/COW/,$word)||$word)
