I thought we had decided that null-environment must take a version
argument, since the set of syntactic forms defined in the environment
specified by the return value of null-environment depends upon the
report version.

Even in the report versions where null-environment does not occur? Hmm...
And do the bound operators all have their semantics from back then?  Like
if I want to have #f and () be eq?  ... What fun.  I hope 0 and negative
numbers can be specified to get the pre-revised reports.  Fun with CATCH
and FLUID. Hmm...

Also, what about the Revised report itself?  Since it was not revised^n,
is n=1 a valid value of null-environment.

I'm so excited by all this.  It's going to do wonders for CL's marketing
when Scheme images are bigger than CL images because they have to hold all
of history in null-environment (what an ironic name, since it will have 5
times as much environment in it as the initial environment does)...
