Because that wouldn't work with routine_id(). If you have several
routines that are ONLY accessed via call_func/proc, there's a
good chance you'll throw away necessary code.

Sure, if routine_id is always given a literal as a parameter, no
problem; but when you have a any sort of variable passed in, this
method won't work.
