The place where a regex really shines is when it's generated at runtime.
A regex literal can be replaced by code. A regex read from a
configuration file is much harder to replace with code (altho less so in
Erlang than some other languages). A regex read from the keyboard is
almost impossible to replace with code.
Sort of like XML - if you don't have CDATA that makes sense when you
strip out all the <tags>, chances are you're using the wrong tool.

Check your feather pillows for holes
before putting them in the washing machine.
