import std.typecons: Nullable;
alias Foo = int[5];
alias NFoo = Nullable!Foo;
NFoo bar1() {
    int[] a;
    return NFoo(a); // Error
}
NFoo bar2() {
    immutable int[] b;
    return NFoo(b); // Error
}
void main() {}



dmd 2.066alpha gives error messages that I think could be better:

test.d(6,16): Error: inout method std.typecons.Nullable!(int[5]).Nullable.this
is not callable using a mutable object
test.d(10,16): Error: inout method std.typecons.Nullable!(int[5]).Nullable.this
is not callable using a mutable object
