Some people will point out that it's faster (or worse, "more  
efficient") but that's infintessimal.

The key is that if you're not using the regex metacharacters, they  
can't screw you up.

What if you have a category called "Income in $US"?  If you match  
that as /$str/, then you're matching /Income in $US/, and that will  
never match because "$" means "end of line."
