No.

- Independently: Is the syntactic distinction between "=" and "=>" a
cognitive burden?
YES!
A few weeks later than the prior long discussion that I read in full, it took a triple take not to read it as >= (which would mean something syntactical in many cases, just not what is intended).
- 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?
I would always recommend against its use if I had any influence on code review.
- 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.)
Yes, the delay/later/defer keyword approach is not confusing, and does not preempt a later feature that would actually be worth having.
5) Do you know how to compile CPython from source, and would you be
willing to try this out? Please? :)
I do know how, but it is unlikely I'll have time.
