fn f(t:for<>t?)
//~^ ERROR: expected one of
//~| ERROR: invalid `?` in type
Remove incorrect assertion in type parsing code 2021-06-04 12:48:24 -05:00			`fn f(t:for<>t?)`
Parse `Ty?` as `Option<Ty>` and provide structured suggestion Swift has specific syntax that desugars to `Option<T>` similar to our `?` operator, which means that people might try to use it in Rust. Parse it and gracefully recover. 2022-01-10 16:02:19 -06:00			`//~^ ERROR: expected one of`
