          Priority: P2

For example:

void main() {
    void delegate()@system x = {writeln("I am @system");};
    void delegate()@safe y = {};
    auto px = &x;
    auto py = &y;
    px = py; // accepts-invalid
    *px = x;
    y(); // "I am @system"
}

The equivalent example with function pointers already results in a compile
error.
