Check if type object is <class 'int'>, <class 'float'>, <class 'string'>, etc

[TNtube]

I'm trying to check if a type object is equivalent to any C++ type i binded, but it seems that i can't really retrieve python type of standard types like those (py::type::of<int>() fail at compile time). I don't mind to write specialization for them, but I can't even find a way to check if a python type object is a int/float.

I guess I could just call py::eval and pass my py::object as a local variable, but I hoped there was a cleaner solution for this.

Thanks
