What the precise difference (semantics and speed) is between the
BINARY_ADD and INPLACE_ADD opcodes, I dunno. Look in the Python source
code or maybe someone knows it from memory :-)

from Python/ceval.c:
1316case BINARY_ADD:
1317w = POP();

For floats it is understandable. But for integers, seriously, 4% is a lot. I

it feels so natural to check it that way, but we have to write
if a = x = b
I understand that it's not a big deal, but it would be awesome to have
some optimisations - it's clearly possible to detect things like that
wrong one and fix it in a bytecode.

You can do something like this:
class A(): pass
inst=A()
exec(
... a=1
... b=2
... c=3
... d=4
... ) in inst.__dict__
inst.a
1
This executes the Statement in the exec function and uses inst.__dict__
as namespace. But be aware, that this is not recommended. If you mess
with __dict__, you
import types
import marshal
def a(): pass
...
s=marshal.dumps(a.__code__)
f=types.FunctionType(marshal.loads(s), {})
f
function a at 0x7f6308a66de8
What version of python do you have? If I try your code above I get :

As you see, the traceback only starts from function c, which handles the
exception.
It doesn't show main(), a() and b(), which might however be (and are, in
my case) critical to diagnose the severity of the problem (since many
different paths would lead to calling c()).
This results in

Hi,
unfortunatley I cannot reproduce your error. Which Python Version do you
use?
The expected case in this scenario is that the exception is thrown, as
you import os in A() where it is stored in the local namespace of the
function.
I tested it with Python 2.4, 2.5 and 2.6 and in both cases an
Python searches for Variables not only in local or global scoop but also
in __builtins__. If you do something like __builtins__.os = os, than
this variable should be accessible global.
If you then write something like:
def B():
os.stat(/)
import os
Python recognises on compile
