Setting up "&" to have a readmacro function
can give ( &REST BAR) => (REST BAR)
(&OPTIONAL A B C D E &REST K) => ((OPTIONAL A B C D E) (REST K))
or whatever else you want.
This is not so good, because &keywords are only defined to have these
meanings in bvl's, but using them as readmacros causes them to be
expanded all the time. True, how often do we use &, so it could be
slashed, but I'm still against having a readmacro that is only useful in
a special place.
