Hi @hypnopump, thanks for your contribution!

Does this change improve performance in a meaningful way?

[hypnopump]

hm not that i was aware of. It was pretty much the same. The thing i saw that could help significantly is in the final construction of suggestion, which uses a set and a list. One could speed that up by using only a set, but unfortunately it wouldn't conserve the order (alphabetical order would be favoured instead)

ok, maybe I had misunderstood the motivation for your PR... It saves a few statements but in turn makes the code harder to read IMHO. Unless there's an actual performance gain, which appears not to be the case, I'd rather not apply the change.
