Chung, you're one of my favorite PHP masters and I learned few things from
you on this group, but the work you're doing has already been done. PHP
runkit extension, by Sara Golemon, has this possibility:

RUNKIT_IMPORT_OVERRIDE (integer)

runkit_import() flag indicating that if any of the imported functions,
methods, constants, or properties already exist, they should be
replaced with the new definitions. If this flag is not set, then any
imported definitions which already exist will be discarded.

This sounds very much like overloading to me.
