This shows how to enable a template for an explicit list of types.
#include <iostream>
#include <type_traits>
template<typename T, typename... UsableTypes>
struct SearchImpl : std::is_same<T, UsableTypes>...
{
};
template<typename T, typename... UsableTypes>
struct Search : std::is_base_of<std::true_type, SearchImpl<T, UsableTypes...>>::type

This shows how to use SciPy's Cython-exposure of the BLAS and LAPACK libraries from within ctypes.
import numpy as np
import ctypes as ct
from scipy.linalg import cython_blas
#ct.cdll.LoadLibrary("libopenblas.dll")
#openblas = ct.CDLL("libopenblas.dll")
#dgemm = openblas.dgemm
ct.pythonapi.PyCapsule_GetPointer.restype = ct.c_void_p
ct.pythonapi.PyCapsule_GetPointer.argtypes = [ct.py_object, ct.c_char_p]

This shows how to wrap a C++ function in a capsule within Cython, how to call a function pointer wrapped in a capsule object, how to export that function as a part of the modules C API, and how to call that function from outside the module using ctypes.
