Passing buffers or sink delegates (like we already do for toString) is
possible for some functions. For toString it works fine. Then implement
to!RCString(object) using the toString(sink delegate) overload.

For all other functions RC is indeed difficult, probably only possible
with different manually written overloads (and a dummy parameter as we
can't overload on return type)?
