I've just updated PEP 671 https://www.python.org/dev/peps/pep-0671/ with some additional information about the reference implementation, and some clarifications elsewhere.
*PEP 671: Syntax for late-bound function argument defaults*
Questions, for you all:
- If this feature existed in Python 3.11 exactly as described, would
you use it?
no because of name=>
- Independently: Is the syntactic distinction between "=" and "=>" a
(It's absolutely valid to say "yes" and "yes", and feel free to say which of those pulls is the stronger one.)
- If "yes" to question 1, would you use it for any/all of (a) mutable
defaults, (b) referencing things that might have changed, (c) referencing other arguments, (d) something else?
yes (a) What does (b) mean? example please. yes (c)
- If "no" to question 1, is there some other spelling or other small
change that WOULD mean you would use it? (Some examples in the PEP.)
Use the @name to avoid the confusing with the set of = things.
- Do you know how to compile CPython from source, and would you be
willing to try this out? Please? :)
no promises, if I get spare time I'll give it a go, should be easy to hack the Fedora python RPM to build your version.
I'd love to hear, also, from anyone's friends/family who know a bit of Python but haven't been involved in this discussion. If late-bound defaults "just make sense" to people, that would be highly informative.
Any and all comments welcomed. I mean, this is python-ideas after all... bikeshedding is what we do best!
The reference implementation currently has some test failures, which I'm looking into. I'm probably going to make this my personal default Python interpreter for a while, to see how things go.
