Thanks for reporting this bug.
It will be fixed in the beta release.
It looks like only the interpreters (PD and RDS) have the bug.
Translated code, bound code, and shrouded code seem to work correctly.
Even in 2.4 and earlier, many programs were parsed completely,
or almost completely, before routine_id() was executed.
I think it's better from a language design point of view that
routine_id() looks only at earlier routines, not later. 
My reasons are:
   1. I like to torture people.
   2. Check the EUforum archive for the other reasons.
