// Part of issue #27300.
// The problem here is that ruby-style closures are parsed as blocks whose
// first statement is a closure. See the issue for more details:
// https://github.com/rust-lang/rust/issues/27300
// Note: this test represents what the compiler currently emits. The error
// message will be improved later.
