issues with clang and registerFunction - probably clang's fault

[ahupowerdns]

Many thanks for Luawrapper, it is amazing, and over at PowerDNS we plan to do big things with it. However, we ran into a snag.
Now this is probably due to clang 3.5 (OSX Yosemite) being wrong. I think it deducts that the function passed is const, which it is not.

Any use of registerFunction on an object errors out with:
./ext/luawrapper/include/LuaContext.hpp:1050:172: error: no matching function for call to object of type 'const std::__1::_mem_fn<void (Object::)()>'

This when compiling:
class Object {
public:
Object() : value(10) {}
void increment() { std::cout << "incrementing" << std::endl; value++; }
int value;
};

int main()
{
LuaContext lua;
lua.registerFunction("increment", &Object::increment);
}

I tried a lot of thing to work around this issue, but short of deleting the registration of the pointer and shared_ptr versions, I can't find anything..

Help ;-)

Same issue here.
