def adds_alias #
Description copied from class Savi::Compiler::Infer::DynamicInfo

May be implemented by the child class as an optional hook.

def first_viable_constraint_pos : Source::Pos #

def infer_from_all_upstreams? : Bool #

By default, a NamedInfo will only treat the first assignment as relevant for inferring when there is no explicit, but some subclasses may override.
