Description

it told me to file a bug

<stdin>:12:17: error: 'consume' applied to value that the compiler does not support. This is a compiler bug. Please file a bug with a small example of the bug
    _ = consume x
                ^

Reproduction

func f() 
{
    let x:[Int] ; x = []
    _ = consume x
}
