Note that 121 is withdrawn, so people should implement 158.

I agree that it's desirable for one of the sample implementations to be
as simple and clear as possible, for the purpose of clarifying the
specification.

Sounds good.  For SRFIs such as 121 and 158, where efficiency is
important, I think that a second sample implementation tuned for
performance would be a useful addition.
