I don't know which people would expect that. Personally I recognize the need to
create an empty array of of given size, and have read the docs for builtin
"bytearray" type, and expect extension type array.array to work the same. I'd
even say that I found any other expectations ungrounded, in particular, a way
to create an array of single int is obviously bytearray([3]) or
array.array('i', [3]).
Anyway, as I say in "2014-04-13 15:29" comment, I'm only glad to follow with
PEP467 changes. Unfortunately, I don't seem to be able to update initial ticket
description with updated proposal.
> array.array('i', len=3)
The whole scope of this ticket is to have consistent API between bytearray and
array.array. So, the only way I could suggest (or back) the above is if PEP467
was changed too, and as you suggest, I don't do that. (I personally also
dislike overuse of keyword args.)

The ending is the saddest. As I mentioned, the best outcome I could imagine of
such reports is that people who consider changing builtin types to also
consider obvious stdlib counterparts too. (There's another issue - stdlib is
indeed enormous, so it would be nice to separate it (speculatively) into
["builtin types/lib"], "core stdlib", and "extended stdlib". There's clear
difference between array module and for example unittest or logging.
Thanks for hint re: mailing Nick Coghlan - nice to know that's acceptable,
that's certainly easier than figuring out which mailing list to use and then to
follow it. (I see that Nick is in noselist of this ticket, but I guess I'll
mail him anyway to have my conscience clear that I did everything to make
Python better (== more consistent)).
