But the strange thing is if I use new.instancemethod the c function
becomes bound (using my previous code for _test.c)
import _test
class Test:
def func1(self):
print "In class "+repr(self.__class__.__namd__)
import new
Test.func2 = new.instancemethod(_test.func2, None, Test)
del new
t = Test
type(_test.func2) # returns <type 'builtin_function_or_method'>
type(T.func1) # returns <unbound method Test.func>
type(t.func1) # returns <bound method Test.func of <__main__.Test
instance at 0x4eb4b8>>
type(T.func2) # returns <built-in function func2>
type(t.func2) # returns <bound method Test.func2 of <__main__.Test
instance at 0x4eb4b8>>
So is seems like it is bound appropriately, but when called across the
C/Python api the first argument (self) of func2 is not separated
from the other arguments (and thus is not sent into the c
function as PyObject* self, but instead as part of PyObject* args)
