That's doomed to fail. You do not account for that a huge number of method calls resolve to code in CPAN libraries, not yours. They do not conform to your sense of order and aesthetics.

I suggest you undo this problem by investigating why you feel that programmers need to guess and search blindly for identifiers. If the identifiers are part of the public API, they should be documented in POD and already spell-checked. If they aren't, then who cares they are guessable - you would look up the name from the code after diving in from an entry point, or Ctags or similar.
