Issue1638882

I ran into this will inspecting test_inspect and saw one of the errors thrown was this problem:

import types

bim = types.BuiltinMethodType
print bim
bim2 = types.BuiltinFunctionType
print bim2
print bim == bim2

print type(list.append)

a = type([].append)
print a

print a == bim
assert a== bim, "not a BuiltinMethodType"

running in python gives us this output:
python testbuiltins.py
<type 'builtin_function_or_method'>
<type 'builtin_function_or_method'>
1
<type 'method_descriptor'>
<type 'builtin_function_or_method'>
1

while in jython we get:
jython testbuiltins.py
<type 'method'>
<type 'reflectedfunction'>
0
<type 'methoddescr'>
<type 'list$1exposed_append'>
0
Traceback (innermost last):
  File "testbuiltins.py", line 15, in ?
AssertionError: not a BuiltinMethodType

wow, this bug gets weirder.
types.BuiltinFunctionType
types.BuiltinMethodType
are ==
type(var) == type([].append)
is true

so this seems to become a bug in types and in PyBuiltinFunction.  types needs to have the Builtin*Types be derived from the same class and PyBuiltinFunction needs to have that type.

patches and further discusion for this is here:

This was fixed by my unification of all the builtin function types.
