Construct closure type eagerly Construct the returned closure type *before* checking the body, in the same match as we were previously deducing the coroutine types based off of the closure kind. This simplifies some changes I'm doing in the async closure PR, and imo just seems easier to read (since we only need one match on closure kind, instead of two). There's no reason I can tell that we needed to create the closure type *after* the body was checked. ~~This also has the side-effect of making it so that the universe of the closure synthetic infer vars are lower than any infer vars that come from checking the body. We can also get rid of `next_root_ty_var` hack from closure checking (though in general we still need this, #119106). cc ```@lcnr``` since you may care about this hack 😆~~ r? ```@oli-obk``` |
