Consider:

cpython/Modules/socketmodule.c

Lines 3423 to 3427 in d3ada45

	if (!PyIndex_Check(optval)) {
	PyErr_Format(PyExc_TypeError,
	"setsockopt() argument 3 for AF_VSOCK must be an int (got %T)",
	optval);
	}

This sets an error, but doesn't return, so the code falls through to parsing optval anyway.
