FWIW, presently the specification somewhat implies that 1.23 is a Num
literal, and doesn't say anything about it producing a Rat.
(Yes, conversations on #perl6 have indicated that it may be otherwise,
but nothing is currently in the spec about it.)
S02:401 :
One consequence of all this is that you may no longer write a Num as
C<42.> with just a trailing dot. You must instead say either C<42>
or C<42.0>.
