Okay, this is an important point, I think. I argue that some sort of
sugar for static storage in fu
Now it seems Python doesn’t need constant. There are many ways we can achieve
constants. Though constants may increase performance. Yet again it can also be
the opposite.

There's been a discussion in this list on extending Python to provide
SYNTAX such as
@decorator
name = EXPRESSION
and also suitable semantics. (Here 'name' is an identifier, in the
discussion called a 'variable'.)
This post is about providing SEMANTICS for such decorator syntax. We can do
Since `dict` now is ordered, how about a `sort()` method?
It could have the same signature of list.sort(), with an optional
parameter "by" that can be "keys" or "values" ("keys" could be the
default).

Or to keep the same dict (not tested)
tmp = list(sorted(d.items()))
d.clear()
d.update(tmp)

With CPython, tracebacks obtained from code written in C can be extremely
clean compared with functionally equivalent code written in Python.
Consider the following test file where I am using a local copy of Python's
datetime.py module.
```py
from local_datetime import date
d = date(2021, 13, 1)

Eg anyio sets __tracebackhide__ = __traceback_hide__ = True to remove
internal frames from user Tracebacks

Thanks for the reminder. Pytest takes care of traceback formatting for
users. Individual projects can of

You can control what the traceback of exceptions you are emitting:
"raise e.with_traceback(None)" should clear everything before the current
frame.
Or you can get clever and construct a traceback with only the frames you want.

Dicts keep their insertion
FWI, this is a previous thread.
