New submission from Terry J. Reedy <tjre...@udel.edu>:
In 3.10 and 3.11:
>>> while s := input.read(MAXBINSIZE):
... while len(s) < MAXBINSIZE and ns := input.read(MAXBINSIZE-len(s)):
File "<stdin>", line 2
while len(s) < MAXBINSIZE and ns := input.read(MAXBINSIZE-len(s)):
^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: cannot use assignment expressions with expression
IDLE only colors the 'l' of 'len'; add extended marking.
Some other errors gained extended location in 3.11 (only, I believe). Adding
colors may require monkeypatching method or subclassing class in traceback.py.
May have commented on issue or PR.
Related: Put SyntaxError in box. (Anyone really want log of error?)
