Not sure this is a good idea.  After all, if +1 would be the "default"
increment for a class #succ would have been implemented that way.  In
absence of a #succ implementation a Range cannot do any assumption as
to how get the next value - that's the exact reason why there is a
method #succ.  You could as well wrap a Time instance in something
that implements #succ accordingly.

Sounds like a bug which is not present in 1.9.2:

=3D> [1.0, 3.0, 5.0]
