Bug#1001295: dominate: needs update for python3.10: 'Callable' from 'collections' is removed

[Paul Gevers]

Source: dominate
Version: 2.3.1-2
Severity: serious
X-Debbugs-CC: debian...@lists.debian.org
Tags: sid bookworm
User: debian...@lists.debian.org
Usertags: needs-update
Control: affects -1 src:python3-defaults

Dear maintainer(s),

With a recent upload of python3-defaults the autopkgtest of dominate 
fails in testing when that autopkgtest is run with the binary packages 
of python3-defaults from unstable. It passes when run with only packages 
from testing. In tabular form:


   passfail
python3-defaults   from testing3.9.8-1
dominate   from testing2.3.1-2
all others from testingfrom testing

I copied some of the output at the bottom of this report. 
https://docs.python.org/3.9/library/collections.html says:

"""
Deprecated since version 3.3, will be removed in version 3.10: Moved 
Collections Abstract Base Classes to the collections.abc module. For 
backwards compatibility, they continue to be visible in this module 
through Python 3.9.

"""
Time to move on.

Currently this regression is blocking the migration of python3-defaults 
to testing [1].
