Ayaz Hafiz cd2b936a59 Ensure that disjoint nested lambda sets force parents to be disjoint ... We must be careful to ensure that if unifying nested lambda sets results in disjoint lambdas, that the parent lambda sets are ultimately treated disjointly as well. Consider ``` v1: {} -[ foo ({} -[ bar Str ]-> {}) ]-> {} ~ v2: {} -[ foo ({} -[ bar U64 ]-> {}) ]-> {} ``` When considering unification of the nested sets ``` [ bar Str ] ~ [ bar U64 ] ``` we should not unify these sets, even disjointly, because that would ultimately lead us to unifying ``` v1 ~ v2 => {} -[ foo ({} -[ bar Str, bar U64 ]-> {}) ] -> {} ``` which is quite wrong - we do not have a lambda `foo` that captures either `bar captures: Str` or `bar captures: U64`, we have two different lambdas `foo` that capture different `bars`. The target unification is ``` v1 ~ v2 => {} -[ foo ({} -[ bar Str ]-> {}), foo ({} -[ bar U64 ]-> {}) ] -> {} ``` Closes #4712		2022-12-12 14:51:18 -06:00
