It's because it has to work in pattern contexts as well, which are not expressions.

Wait, in pattern context? How? Can you give an example?

[–] 0v0@sopuli.xyz 10 points 6 months ago 
fn foo(x: i32) {
    match x {
        const { 3.pow(3) } => println!("three cubed"),
        _ => {}
    }
}

But it looks like inline_const_pat is still unstable, only inline_const in expression position is now stabilized.
