[racket] read of numbers with decimal point default to exact?

>> 5.55 and 1.11 are read as inexact reals, which are flonums. In fact in

>> There is good reason to distinguish exact reals from inexact ones, because

I think Neil understands the above perfectly well; as I read it, his suggestion was
that, *by default*, the Racket reader should choose correctness over efficiency,
while allowing the programmer to choose efficiency (via exact->inexact) if (s)he
wishes.
