Also, you may want to consider the /x modifier to avoid
"regex blindness", [a visual Bermuda Triangle that will
cause anyone viewing it to avert their eyes and quickly
paddle the other way].
Even with an easy regex, the view improves considerably
with /x :
if ( / \w{7} \s \w{4} \s # insert comment here...
\d{1,4} # more comments...
....
/ix )
Or just:
/ \w{7} \s \w{4} \s .... /ix; # whitespace enhanced
