Disallow cast with trailing braced macro in let-else This fixes an edge case I noticed while porting #118880 and #119062 to syn. Previously, rustc incorrectly accepted code such as: ```rust let foo = &std::ptr::null as &'static dyn std::ops::Fn() -> *const primitive! { 8 } else { return; }; ``` even though a right curl brace `}` directly before `else` in a `let...else` statement is not supposed to be valid syntax.
