Runtime slice of zero-sized pointer assigned to _ yields strange compile error

[SpexGuy]

// repro.zig
export fn foo() void {
    var x: usize = 4;
    _ = @as([*]void, undefined)[0..x];
}

<source>:5:32: error: expected type 'void', found '[]void'
    _ = @as([*]void, undefined)[0..x];
                               ^

Replacing _ with var y or const y fixes the error.

with latest compiler:

• compiler no longer errors
• appears this was fixed between 0.9.1 and 0.10.0

repro.zig

export fn foo() void {
    var x: usize = 4;
    _ = @as([*]void, undefined)[0..x];
}
