No, I still can't think of a case where you'd pass routine_id an
unrecognised string and want it to return -1 quietly instead of
stopping with an error. Rob claims it would break existing code.

In Diamond, I use it in method definitions to have the program crash under
my control, doing cleanup and producing a Diamond standard error message. If
we had crash_routine, I could live with a bad routine_id crashing, but this
would still break the include detection code CChris mentioned.
Here's a technique to wrap routine_id at the top of the file:
function Eu_routine_id(sequence x)
return routine_id(x)
end function
global function routine_id(sequence x)
integer rid
rid= Eu_routine_id(x)
if rid >=0 then return rid end if
?1/0
end function
