    My BNF, and the current RRRS, say that DEFINE's can't occur in
    BEGIN's; does anyone have any problem with that?  If so, what
    should it mean?

I have a small problem with that: as always, it is necessary to be
able to write macros that expand into multiple definitions.  So MIT
Scheme takes the position that a BEGIN appearing anywhere that a
DEFINE may appear is allowed to contain DEFINEs.  This seems to solve
the problem perfectly adequately, and is very easy to implement.
