Const generics: Wrong number of const arguments

[Centril]

The following should type check but does not:

#![feature(const_generics)]

fn foo<const N: usize, const A: [u8; N]>() {}

fn bar() {
    foo::<_, {[1]}>();
}

Errors with:

error[E0107]: wrong number of const arguments: expected 2, found 1
 --> src/lib.rs:6:5
  |
6 |     foo::<_, {[1]}>();
  |     ^^^^^^^^^^^^^^^ expected 2 const arguments

error[E0107]: wrong number of type arguments: expected 0, found 1

  |           ^ unexpected type argument

  = note: expected type `usize`
             found type `[{integer}; 1]`
