You may be interested to know that the output of:

$str = "ABCDEFGHIJKLM";

while ($str =~ /(BC|GH|LM)/g) {

  print "matched $1\n";
}
[download]

is:

matched BC
matched GH
matched LM
[download]

Which I think is what you needed. You'll get a match line for each of them, so long as they don't overlap.
