create type ascription for any cast Also, avoid shadowing of the `ty` variable by giving the `cast_ty` and `var_ty` variables different names. We want to get the user-provided type from `cast_ty.hir_id`. 2018-10-17 15:18:24 -05:00			error[E0597]: `x` does not live long enough

Use new region infer errors for explaining borrows This gives at least some explanation for why a borrow is expected to last for a certain free region. Also: * Reports E0373: "closure may outlive the current function" with NLL. * Special cases the case of returning a reference to (or value referencing) a local variable or temporary (E0515). * Special case assigning a reference to a local variable in a closure to a captured variable. 2018-10-14 09:12:02 -05:00			`\| ^^^^----------------`
