Actually a char[] is not a valid output range. Overwriting

Hm... I think it should be, and here is why. Imagine this situation:
char[1024] buffer = void; // allocate some blank space on the stack
put(buffer, someInputRange);
But the above won't compile anyways, because a ref char[1024] isn't a
range, and even if it was, it would be left in a state where it pointed
to the uninitialized data. What we need is a helper struct, and then we
are covered.
char[1024] buffer = void;
CharBuilder builder(buffer[]); // defines put
put(builder, someInputRange);
So I think we are good. Does Appender work here?
Appender doesn't currently work with fixed-size buffers, but it could
and should be made to work. It's a good idea.
