Type modifiers can't be passed around in the language, but I think there's a
separate issue already opened for this.

Anyway you can do:

import std.traits;

ref uint foo(ref uint num) {
    return num;
}

void main()
{
    alias FunctionAttribute FA;
    static assert(functionAttributes!foo & FA.ref_);
}
