[issue25737] array is not a Sequence

[Josh Rosenberg]

Josh Rosenberg <shadowranger+python at gmail.com> added the comment:

This should not be closed as a duplicate. Yes, array.array isn't automatically a Sequence, but since it isn't, the array module should be modified to explicitly do the equivalent of:

import _collections_abc

_collections_abc.Sequence.register(array)

so it's properly registered manually.
