There's a lot of bloat in an xsub with FREETMPS, and getting things from
the stack and putting them back for the return, and whatnot. Most of
it's due to perl doing too much inlining. A threaded build comes out
particularly bad. Some combining saves code space when it can be done
conveniently. The difference between one or two funcs in this case
won't be huge, but the same in lots of places will add up.
Nice to know! I will start to apply your advice to my bindings.

There are actually :-). I assume the original poster either didn't get
to the stage of running them, or didn't run them in an X display
session.
