[r6rs-discuss] [Formal] string output ports

[Per Bothner]

I think there is another problem, which is not string-port-specific,
but touches on it:
Can open-string-input-port and open-string-output-port be
implemented using only public library functions?  This is
important, IMO.  There is a make-custom-binary-input-port,
but I don't see a make-custom-textual-input-port.  Can the
latter be implemented sanely on top of the former?  I suppose
it could in theory, but it seems very wrong.

It should be possible to implement transcoded-port (or something
with very similar effect) using make-custom-textual-input-port
and make-custom-textual-output-port.
