Can't use self_referencing with must_use macro

[rluvaton]

When I do:

use ouroboros::self_referencing;

#[must_use = "something"]
#[self_referencing]
struct MyStruct {
    int_data: i32,
    #[borrows(int_data)]
    int_reference: &'this i32,
}

The error is:

Unsupported attribute

I found a similar issue a while back around derive that might be related
