# Unexpected warnings are failures: warnings are load-bearing API in 2.0
# (the multi-word-entry UserWarning, the facade deprecation warnings), and
# without this a warning regression is invisible to the suite -- a real
# bug (eight spurious warnings on restoring a 1.4 Constants pickle)
# shipped to review this way. Tests that EXPECT a warning assert it with
# pytest.warns; targeted ignores below need a comment justifying each.
