          Issue ID: 21445
           Summary: Indexing a tuple in a static array type suffix fails
                    to compile
           Product: D
           Version: D2

import std.typecons;

enum s = tuple(new int[1]);
int[s[0].length] a;

void main() {
}

onlineapp.d(4): Error: Tuple([0]) must be an array or pointer type, not
Tuple!(int[])

Workaround:

enum t = s[0];
int[t.length] a;
