Yeah, but the one operation it replaces, ~=, can be done
on an array.

If you're trying to convert array code to Appender for
speed, most likely you're going to be replacing a
bunch of ~= calls.

It's ok if the other op don't compile, but this one
really should. Appender, regardless of the internal
representation vs array is a speed optimization;
an implementation detail.

It's also an Appender, though. I think it is a little
silly to have an Appender to which you can't /append/.

(put is great too, don't get me wrong, but so is ~=).
