Typ? "Both", then you state two different things.

AFAIK, anything returnable can be qualified with const, so there would be no
fall through case.

What about:

--------
struct S
{
    const nothrow pure
    T foo();

    nothrow pure const
    T bar();
}
--------

What does (should) foo return? What about bar?

The current rules are obvious: stand alone attribute => Function.
Simple and obvious.
There is no reasons for "const" to get special treatment.
