Looks like dmd doesn't realize that it's a function call between the brackets.
Adding empty parentheses is a workaround.

Here's a slightly smaller test case that shows a different error, but I suspect
the same root cause:
----
int bug() { return 0; }
void main()
{
    int[bug()] bar1; /* works */
    int[bug] bar2; /* Error: index is not a type or an expression */
}
