You say that as if text strings aren't sequences of bytes. Complicated

Thanks everyone for the feedback and suggestions. I agree that there are many
ways one could easily implement this (chaining, reduce, looping, etc.). I
could continue to maintain a utility function and copy that around to all of
code bases where I need this functionality, which is what I do to

It seems most of the folks on this thread have similar feelings on this, so I
will drop this idea. We'll probably standardize on using glom for now.

ConfgObj used to have a similar method I believe. From fetching a value
from a nested section by supplying the full path (as an iterable I believe).

With my implementation, I can check
assert int | None == None | int
is true

Hello,
I propose to resume all the arguments (I add my remarks in italic) and
major questions.
Add a new operator for `Union[type1|type2]` ?

way back at the very beginning of the type-hinting discussion, and the
Regarding the discussion about using the tilde operator (an idea which has
grown on me a bit):
Would it help, for the purpose of alerting the user to potential backwards
compatibility issues, to add a *second* dunder method, __optional__, or
perhaps __tilde__. to the tilde operator resolution ord

Hold on. Are you proposing `Union[t1 | t2]` as a new spelling for `Union[t1,
t2]`? That seems pointless. I thought you were proposing just `t1 | t2`, which
seems a whole lot more useful (and no m

It's not *necessary* it's just nicer.

It sounds like you may be asking about two different things:
* adding more distinct platform tags for wheels to use for AIX,
indicating... a minimum OS level, if I'm connecting the dots correctly.
This would be like what PEP 513 did with `manylinux1` for Linux, and PEP
571 is doing for the new-and
