+ As per usage examples, clause literals are a list of strings. + Note: symbols extracted from literals are expected to be exactly two characters. + self.literal boolean values are initialized to None, so must be optional + model values should be Booleans, but aren't guaranteed to be non-None in the code. + uses newer '... | None' annotation for Optional values + clauses are passed to the Formula initializer as both lists and sets, they are stored as lists. Returned clauses will always be lists. + use explicit tuple annotation from __future__ rather than using (..., ...) in return signatures + mapping returned by dpll_algorithm is optional per the documentation.
