There are two of them:

template<class T> unsigned GetHashValue(T *)

and

template<class T> String AsString(T *)

means it is now not required to provide GetHashValue for pointers and pointers can be e.g. DUMPed directly.

Hi mirek

i ran into a dumb problem since that..

this used to work (Python export of a class, say 'Size')

		.def("__str__", &::AsString<Size>)

now, TDMGCC451 still compiles it, MSC9 doesnt.
I could wrap this into an explicit differently named function, but this is a general problem.. how to get a pointer to that function?
casting to an explicit version doesnt work as it seems

		.def("__str__", (String (*)(const Size&))&AsString<Size>)

any hint?

This is really sad. IMO it is not 'our' bug....

What about adding AsStringConcrete template (same definition as AsString), which is NOT defined for pointers?
