This is a spinoff of Issue 8751


alias bool delegate(in int) pure Dg;
Dg foo1(immutable Dg f) pure {
    return x => f(x); // OK
}
Dg foo2(const Dg f) pure {
    return x => f(x); // error
}
void main() {}


DMD2.060alpha gives:

temp.d(6): Error: cannot implicitly convert expression (__lambda4) of type bool
delegate(const(int) x)  system to bool delegate(const(int)) pure
