This PR exposes the
pop_exception_handler
andpush_exception_handler
totraits.observation.api
, hence making theexception_handling
module public.traits.api
also has a pair ofpop_exception_handler
andpush_exception_handler
foron_trait_change
.These two handlers are typically used in tests for reraising exceptions.
Sorry for the last minute additions to the public API.
