Yeah, use the "actual" std.range.put:

//----
void main()
{
    // Error: casting string to char is deprecated
    // Error: static assert  "Cannot put a dchar into a Appender!(string)"
    Appender!string x;
    put(x, repeat(" ", 4)); 

    // Error: casting string to dchar is deprecated
    Appender!dstring y;
    put(y, repeat(" ").take(4));
}
//----

This is why you should "never" use put "UFCS-style".
Always "put(a, b)".

Now, when all that is said and done, there's still an internal error, so it
needs fixing.

I don't think "Appender" should be able to handle this "natively" though. It
should have given a "no matching function" error.
