...and if we also (or instead) want to have a universal method for getting
Perl 5-style memory address hashes ("FOO(0x12345)"), then that should have a
name without the phrase or idea of "identifier" anywhere in it, IMO:
"memhash", "memaddr", etc.

Other common names for the proposed .id are: UUID: Universal Unique Identifier (DCE) http://www.opengroup.org/onlinepubs/9629399/apdxa.htm GUID: Globally Unique Identfier (EFI) http://ulita.ms.mff.cuni.cz/pub/techdoc/ia64/EFISpec_092.pdf (page 319) Of the 2, usage of "GUID" seems to be more common IMHO.
