Right,

(0..(1.0/0)).each { |o| puts "my_range includes " << o.to_s }

It's not indeterminate, it's a definite infinity (within the
computers' capabilities, of course).  There's a difference.  I suppose
if you use a check within the loop, that might help the use case, but
it still screams of language infidelity.

Of course, I'm just assuming the OP wants 1 to some undetermined
number as an object (a duck) that will quack yes at being asked if
it's a Range.

I'm still trying to figure out why you would want a Range object --
which, by usual definition -- is a _not_ open-ended, have an infinite
side.
