I'm not in favor of changing the whole Scheme IO system. I think that
90% of the features you would like to add to Scheme with SRFI 66 could
be more or less obtained by adding "procedure ports" (ports that
invoke a procedure when read is invoked). I think that adding a new
kind of port is far more lightweight that designing a brand new IO
layer which, I think, is out of scope for R6.
