in thread RegEx Beginning of line or whitespace match

See, I knew this wasn't as difficult to the level I was struggling with it. This works, because I forgot two additional test cases...that being that this could be anywhere in the line, not just at the beginning with or without spaces. e.g.

$line = 'could be anything here some_for($var)'; #don't match
$line = 'could be anything here for($var)'; #match

In other words: match if for( begins at a word boundary, don't match in all other cases: `m/\b(for\()/` PS: you can drop the parentheses if you don't want to extract anything and only want to test for matches.
