This class is remarkably pointless.

We could trash it and change our toStringBuf() methods
to just return a String. I guess. Then the caller would
have to assign the string somewhere. I guess this has some value.

So anyway: Occam's razor, and fixes a small bug: appending undefined
would print as "null" since it was being forced to an Object first.
