With this solution, I see 2 drawbacks :

1 - I have to add a class in my C++ hierarchy only
for XS. And I would like to have a clear spearation
between my C++ classes and my XS code.
I do not want to mix both .
Moreover, my C++ classes are not only mapped to perl but
also to TCL.

2 - I will need to have one typemap for each mapped classes.

am i right ?
