This code displays an error:

-------------- main.d ----------------------
import std.range;
pragma(msg, ElementType!(void[]));
------------------------------------
dmd -c main
void
std\array.d(357): Error: [i] has no effect in expression (a[0u])

I think that this error message should be removed.


If there is not an objection, I rewrite ElementType template as this:
------------------------------------
template ElementType(R)
{
    static if (is(typeof({return R.init.front();}()) T))
        alias T ElementType;
    else
        alias void ElementType;
}
------------------------------------
