This is fine so far, although the mapping for CORBA long is Python int,
not Python long (which is an arbitrary scale integer). long can be used
where int is expected, though, so you'll get away with it.

This is the problem. You're setting the value in the struct to an Any
that itself claims to contain an Any, but you've put in a list of param
structs. It will work if you use idlfile._tc_ParSeq, which is the
TypeCode of your ParSeq typedef.

This seems like a very contrived and complex example.
