usually a great way to go. however when parsing, there's no good way to get
around the literal difference v. abstract differences between 'new wBug (
$myVar' or 'new wbug($myVar' or any other variation. all are the same
when seen by php, but not by strpos - which looks for literal string
occurances. regex can more easily account for any variation of 'new wBug'
and return exactly what the op is looking for.
