New submission from Ben Longbons:
Background:
I have a data hierarchy with a lot of "sibling" symlinked directories/files. I
want to glob only the non-symlink files, because it's a *huge* performance
increase.
Before `os.scandir`, I was using a local copy of `glob.py` a

Code objects currently have no mutable fields.
So what are you planning to do about things like:
Foo = namedtuple('Foo', 'x y')
def frob(self):
return self.x + self.y
# probably actually done via a @member(Foo) decorator
# so adding more code here
New submission from Ben Longbons:
The following code is allowed by the grammar of Python 3.4, but not Python 3.5:
`def f(): g(*a or b)`
where unary `*` has the lowest precedence, i.e. it is equivalent to:
`def f(): g(*(a or b))`
The cause of the regression that the 3.4 grammar for `arglist

Also consider:
*() or (), *() or ()

Actually, I think `star_expr` will probably go

This kind of debug your code is the kind of thing I've gotten used to from
the Clang C/C++ compiler. Granted, compiled languages have an advantage here,
but enough residual information remains for the interpreter at runtime.
And I am
New submission from Ben Longbons b.r.longb...@gmail.com:
I frequently construct lists of tuples, such as:
[
(1, 2, 3) # oops, missing comma!
(4, 5, 6)
]
It would be nice if the error message gave a hint on what was *actually* wrong.
Although I always use homogeneous containers, the type

Yeah, this is a duplicate of issue 6975.
Sorry also about the version thing.
