There was a problem hiding this comment.
my initial idea which made me visit this code was, whether we can cache the TypeSpecifierContext per CallLike, in case its a native non-conditional return type of a single-variant callable.
turns out I cannot detect at this level whether the return type is conditional, because its already resolved.
any idea how I could do it instead?
update: found a way #4817
