That's fine by me. I guess what's more important to me is that code object
have a central, linkable definition *somewhere* (and not necessarily that this
somewhere be a glossary entry). That way references to code object in the docs
can link to a definition

What behavior do you expect? By accident, I found your reply to this

The problem is a regression in the latest version of ActiveTcl 8.5 for OS X,
specifically 8.5.12.1 (and I believe the previous version 8.5.12.0). It has
nothing directly to do with Python or how you might build Python other than
whether _tkinter.so dynamically

If sysconfig._generate_posix_vars() creates the build directory and

I've removed the invocation of the wrapper code in our project, but the issue

I agree with Bryan. Further, if the string is being interpreted as Tcl, then

I've closed the issue as 'wont fix' because llvm-gcc will miscompile 3.3 due to

even possible).

I agree as well. The bigger question is, as Eric suggests, is this the only

All of the optimisations that assume globals haven't been shadowed or rebound

E.g. print(1.5) and print(1.5) are valid for *our* print function, but we
technically have no idea if they're equivalent in user code.

STINNER Victor added the comment:
All of the optimisations that assume globals haven't been shadowed

My main idea is that the developer of the application should be able to
annotate functions and constants to declare them as optimizable (constant).

Any stdlib AST optimiser would need to be substantially more conservative by
default.

minor (?) failures:

* test_pdb: it looks

No, you're assuming global program analysis and *that is not a valid

One of the key features of Python is that *monkeypatching works*. It's not

Method calls on literals are always fair game, though (e.g. you could
optimise a b c.split())
What about optimizations that do not change behavior, except for different
error messages? E.g. we can change
y = [1,2][x]
to
y = (1,2)[x]
where the tuple is constant

I find that the importlib documentation is a bit too low level. Import hooks

Nick Coghlan added the comment:
The peephole optimiser already makes optimisations like that in a couple of
places (e.g. set - frozenset):
def f(x):
...if x in {1, 2}: pass
...
f.__code__.co_consts
(None, 1, 2, frozenset({1, 2}))
It's name lookup semantics that are the real minefield.
Eugene Toder added the comment:
If I'm not missing something, changing
x in [1,2]
to
x in (1,2)
and
x in {1,2}
to
x in frozenset([1,2])
does not change any error messages.
Agreed that without dynamic compilation we can pretty much only track literals
(including functions and lambdas) assigned
