Me too. I have often longed for a wrapper function for routine_id, but
as noted Eu does not play fair. A suggestion springs to mind:

global type rtnid(object r)
	return not equal(r,-1)
end type

Use that type instead of integer for any local routine_id variable
definitions, and also in win32lib etc:

global procedure setHandler(integer id, integer flag, rtnid rid)
...
and either force use of removeHandler, or force {-1} rather than  -1
for the delete feature of setHandler.

Regards,
Pete
PS the type above should be part of the new standard library.
