a totally different parser engine just for that, and there are lots of corner
cases that would break this approach and would need a different approach,
requiring a long list of caveats, and at least personally, I just don't see the
value there. The few places where it seems like it would be a benefit are
pretty small, and the places where it makes things more complex seem common.

First of all, I suggest splitting this into a separate proposal (new thread)
that way you will avoid confusion for people who are still considering the
older proposal, and for the (probably many) people who have stopped reding the
old thread due to some of the more heated conversations in there.

So... how does one go about suggesting changes to the built in types? I could
take a whack at the code for it, but my C skills are no where near what should
probably be needed for something this close to the core of the language. I'm
not sure if adding a couple of methods is a PEP type of thing.

If I am reading this correctly... you have something like (you will have to
excuse my lack of knowledge about what kinds of information these actually are):

5678

And you want something like:

meetings = [(1,'first')

Yup.. another reason to use something like argparse... you define the argument

Theory, each approaches it in
its own way, and each has its own benefits and challenges. This is a perfectly
valid question (and a good one), but don’t let yourself get into the trap of
feeling that Java is the definitive/best/only approach to OO (or Python for
that matter, or C++, or whatever!).

Actually, I think that was the complete code... give it a try...
"{:02}".format("1")
produces the error listed.
I agree the error is not very clear, since the "=" was not passed, it seems
like an incorrect error. What about something like:
"ValueError: '=' and '0' padding are not allowed in s
