This looks like an even better way to do it.
Thanks, Ali :)
Just FYI, the reason this is faster is because there is no need
to go through the opaque calls into druntime to figure out if
appending-in-place is possible. The reserved length is stored
directly in the struct.

That's good to know, thanks :)
By the looks of it, Appender is half duplicating the runtime :)
