On: The PEPs of Python 3.9

[joshuamorton]

On non-iterable strings: The recursive type problem can be solved, with something like what is proposed in [0]. (I have an implementation of a fix on github linked from that thread, there's edge case fixes and PEP's scare me, but technically it's feasible).

While that may solve the recursive type problem, it doesn't really solve the "iterating over strings is rarely what you actually want to do" problem.
