Const generic arguments require brackets (although #60804 is fixed)

[qwerty19106]

The #60804 issue is closed.
But brackets is required yet in my case:

#![feature(const_generics)]

struct Array<const SIZE: usize> {
    data: [u32; SIZE],
}

unsafe impl<const SIZE: usize> Sync for Array<SIZE>
{
}


struct Config {
    size: usize
}

const CONFIG: Config = Config {
    size: 5
};

static SINGLETON: Array<CONFIG.size> = Array {
    data: [0; CONFIG.size]
};

Gives error:

error: expected one of `!`, `(`, `+`, `,`, `::`, `<`, or `>`, found `.`
  --> src/lib.rs:20:31
   |
20 | static SINGLETON: Array<CONFIG.size> = Array {
   |                               ^ expected one of 7 possible tokens

playground

This code is compiled succesful:

static SINGLETON: Array<{CONFIG.size}> = Array {
    data: [0; CONFIG.size]
};

This is expected, only literals and const parameters do not require braces (I believe)
