I think this used to be accepted:


enum Foo : uint { A, B, C, D, E }
void main() {
    static immutable uint[5] a1 = [0, 1, 2, 3, 4]; // line 3
      auto a2 = cast(immutable(Foo[5]))a1; // OK
    static a3 = cast(immutable(Foo[5]))a1; // line 5, error
}



test.d(3): Error: cannot implicitly convert expression ([0u, 1u, 2u, 3u, 4u])
of type immutable(uint[5u]) to immutable(Foo[5u])

Also the error line number is wrong, the right line number is 5.
