import std.array;
void main()
{
    void[] a = cast(void[]) [ 1, 2, 3 ];
    a.front;
}

yields:
..\src\phobos\std\array.d(419): Error: [i] has no effect in expression (a[0u])
..\src\phobos\std\array.d(5): Error: template instance std.array.front!(void[])
error instantiating

Originally I used std.file.read(), hence the void array.

- 1st message is completely senseless, what "[i]"?
- 2nd message shows line 5 which is the line of "a.front;" but the filename is
wrong.
