I do not know exactly what the Run-Kit extension allows you to
re-define -- I only know that it lets you re-define a LOT of low-level
PHP stuff on the fly...
It may not be possible at all to introduce a new keyword with run-kit.

If one is simply mapping:
public action foo
into:
public function foo
then the line number isn't going to change, and, assuming you've been
reasonable about generating the real PHP code, the filename won't
change, just the directory.
