Fixed: Consider using {} instead of a call to 'dict' (use-dict-literal)
Fixed: Unnecessary parens after '=' keyword (superfluous-parens)
Fixed: Metaclass class method __new__ should have 'mcs' as first
argument (bad-mcs-classmethod-argument)
Added: Raising too general exception: Exception (broad-exception-raised)
to the ignore list
This new warning should be addressed in a follow-up patch, not in a
quick fix for unblocking the CI.
