[issue24848] Warts in UTF-7 error handling

New submission from Serhiy Storchaka: Trying to implement UTF-7 codec in Python I found some warts in error handling. 1. Non-ASCII bytes. No errors: >>> 'a€b'.encode('utf-7') b'a+IKw-b' >>> b'a+IKw-b'.decode('utf-7') 'a€b' Terminating '-' at the end of the string is optional. >>> b'a+IKw'.deco

[issue24849] Add __len__ to map, everything in itertools

New submission from flying sheep: Things like progressbars want len() to work on iterated objects. It’s possible to define __len__ for many of the iterables returned by itertools. some arguments have to be iterated to find the len(): of course we have to check if those are reentrant, and raise

R. David Murray added the comment: No, you may not iterate the iterator in order to compute the len, because then the iterator would be exhausted. In addition, the point of itertools is to *lazily* do operations on iterables of indefinite length, so to offer __len__ if and only if the argumen
