To clarify my statement: I did not imply that R6RS aims at making
Scheme harder to implement. For me, I see R6RS as a vehicle for
serving the *users* of Scheme first and foremost. If serving the
users leads to (as a consequence) raising the bar for implementors
and forcing them to implement features that they would rather not
bother with (full numeric tower, useful I/O, unicode, hash tables,
records, libraries, exceptions, ...), then so be it. As a master
Scheme implementor once said: There is no pity for the implementor.
