For now, when we have a __gmp_expr<T,G>, Assignable say : "ho, I have a specialisation which say it is a mpz_class" but in fact, is is not really a mpz_class. It is for exemple a __gmp_expr<mpz_struct, gmp_binary<__gmp_expr<mpz_struct,mpz_struct>,double,binary_plus> > or something like this. As you can see, in fact this is the result of an addition between a double and a mpz_class and it should be a mpf_class because we can see a double in this expression. But it should be more complicated otherwise gmp developper may have fix this problem isn't it?OK I got it. Pythran cast the result to long and python to float, because we do not try to expand the __gmp_expr...Or __gmp_resolve_expr __gmp_resolve_temp ...
