In the Python/C API, conversion functions which check the types of their arguments have names like: double PyFloat_AsDouble(PyObject *pyfloat); while conversion macros that don't check have names like: PyFloat_AS_DOUBLE(pyfloat) The pyldb_Ldb_AsLdbContext() macro looks like one of the checking functions but it actually isn't. This has fooled us more than once. Here we fork the macro into two -- one which performs checks and keeps the camel case, and one with a shouty name that keeps the check-free behaviour.
