Subject: [PATCH] Python: fix using `-builtin -modern -modernargs` results in
segfaulting code (#256)
From 416277b3a56646c2934ca9ee542a3f36d4f9a436 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Python code generated with '-builtin -modernargs' segfaults
for any method taking zero arguments.
Also fixes: "SystemError: error return without exception set" during error checking
when using just -builtin and the incorrect number of arguments is passed to a class
method expecting zero arguments.
Closes #256
Closes #382
