This is a special case, and for the most part it won't make
any difference unless there are auxiliary keyword conflicts.

We do provide a way for the user to write their own REPL
with precise bindings using (environment ...), which is
probably the best way to handle that situation.  But every
implementation out there initializes their REPLs with
a set of bindings, and students expect to be able to
run simple examples when presented with a prompt,
so I don't think we can specify the initial REPL is empty.
