so I think we should be symmetrical between functions' arg list and template arg list
and hence:
- move out of demangle_datatype non real data types ($$V as you did, Z for ...)
- handle the end of list cases before calling demangle_datatype

something like this could do [err](/uploads/314e62b635f2bfcfce46544ac03aaef1/err)

(not ready for inclusion yet: we don't have test for generating template arg list as '<>')
