Bug 6566 – Length of run-time constant array

I think this code shows a DMD bug, I think Foo!(a3) too has to compile: template Foo(alias V) { alias int[V.length] Foo; } void main() { enum int[2] a1 = [1, 2]; Foo!(a1) b1; // OK int[2] a2 = [1, 2]; Foo!(a2) b2; // OK const int[2] a3 = [1, 2]; Foo!(a3) b3; // Error } DMD 2.055head gives: test.d(9): Error: Integer constant expression expected instead of (a3[] = [1,2]).length test.d(9): Error: Integer constant expression expected instead of (a3[] = [1,2]).length test.d(9): Error: Integer constant expression expected instead of (a3[] = [1,2]).length test.d(10): Error: template instance test.main.Foo!(a3) error instantiating test.d(9): Error: Integer constant expression expected instead of (a3[] = [1,2]).length

This seems to work now with 2.062 head Unlike the similar problem in issue 5922
