I'm unsure what is happening here :thinking:

The faultive line seems: https://github.com/pytries/marisa-trie/blob/a1dc368eb0b7d7e481a1663f80dfabefa942aec8/tests/test_trie.py#L135

As of now, I've no idea at all, and thanks for the report :)

BoboTiG commented 7 months ago

The feature was added in v1.0.0 with #90.

@duilio, out of curiosity, do you have any clues?
