typing: suppress bogus pytype errors in `mercurial/wireprotov1peer.py` Fixes: File "/mnt/c/Users/Matt/hg/mercurial/wireprotov1peer.py", line 100, in result: No attribute '_peerexecutor' on unsentfuture [attribute-error] File "/mnt/c/Users/Matt/hg/mercurial/wireprotov1peer.py", line 278, in close: No attribute 'shutdown' on None [attribute-error] Called from (traceback): line 123, in __exit__ File "/mnt/c/Users/Matt/hg/mercurial/wireprotov1peer.py", line 278, in close: No attribute 'shutdown' on None [attribute-error] In Optional[concurrent.futures.thread.ThreadPoolExecutor] We drop the zope decorator on `peerexecutor`, because otherwise it triggers this error: File "/tmp/mercurial-ci/mercurial/wireprotov1peer.py", line 111, in <module>: Invalid type annotation [invalid-annotation] Must be constant Not sure why, because the decorated classes usually get typed as `Any`, which would also be fine here.
