Carl Meyer a04375173c [ty] fix unpacking a type alias with detailed tuple spec (#19981) ... ## Summary Fixes https://github.com/astral-sh/ty/issues/1046 We special-case iteration of certain types because they may have a more detailed tuple-spec. Now that type aliases are a distinct type variant, we need to handle them as well. I don't love that `Type::TypeAlias` means we have to remember to add a case for it basically anywhere we are special-casing a certain kind of type, but at the moment I don't have a better plan. It's another argument for avoiding fallback cases in `Type` matches, which we usually prefer; I've updated this match statement to be comprehensive. ## Test Plan Added mdtest.		2025-08-18 17:54:05 -07:00
