Bug 8442 – [2.060 beta] Empty array enum not treated as immutable

------------------------------------- enum int[] fooEnum = []; immutable fooImmutable = fooEnum; ------------------------------------- testImmutableEnum.d(2): Error: cannot implicitly convert expression ([]) of type int[] to immutable(int[]) ------------------------------------- Worked on 2.059. If fooEnum is *not* empty, the problem disappears.

If empty array literal has the type T[] and T isn't void, should check proper element type convertible (T[] to U --> T to U). https://github.com/D-Programming-Language/dmd/commit/c607144504055bb16eb366e90e2af9e34e8bdac9 Merge pull request #1065 from 9rnsr/fix8442 Issue 8442 - [2.060 beta] Empty array enum not treated as immutable

D1 has similar problem. const int[] fooEnum1 = [1]; const int[] fooEnum0 = []; void main() { const int[1] fooImmutable1 = fooEnum1; // OK const int[0] fooImmutable0 = fooEnum0; // Error // test.d(2): Error: cannot implicitly convert expression ([]) of type int[] to int[0u] }
