When writing a regex that has multiple patterns in it, it would be nice to know which of the patterns matched. I've looked around and can't seem to find what I'm looking for. For example: 
$pat1="field";
$pat2="f.i.e.l.d";
$pat3="the";
$str = "There are many soccer fields in England - f1i2e3l4d";

while($str =~ m/($pat1|$pat2|$pat3)/ig){
   print "Found '$1' from pattern ??\n";
}

What I get is:
Found 'The' from pattern ??
Found 'field' from pattern ??
Found 'f1i2e3l4d' from pattern ??

What I'd like is to find the syntax to replace ?? with the matching pattern:
Found 'The' from pattern 'the'
Found 'field' from pattern 'field'
Found 'f1i2e3l4d' from pattern 'f.i.e.l.d'

Any thoughts?
