Things get overlooked in the confusion, I often have ten things to learn 
all at the same time.  I'll sometimes take some code on faith and forget 
that I've forgotten to really understand it.  Or that an explanation was 
there previously.

I think I might:  Because it's a negation, you have to force the match 
to include the entire element from beginning to end.  You're sorta 
forcing a greedy match.  " ^$foo " searched for in " xxxfoobarxxx " will 
match " xxxfo " but will not match the whole string -- which is to say 
that it matches and therefore is rejected by the caret forcing 
negation.  It's not a simple construction.  Oh, and I would never have 
figured it out by myself, too many things have to work together just right.
