For comparisons, how are we going to use Inf and NaN? Are those going
to be special flyweight objects, so:
$x = 1 / 0;
$x == Inf; # is it the same value
$x === Inf; # it is always the same object
Be mindful of the difference between value types and non value types.
For value types, the generalized value equality test === can return
true for 2 objects if they have the same value, but for non value
types, === tests if they are the same object. All built-in number
types are value types, so === and == would return the same answer for
them. By contrast, the =:= operator always tests if 2 things are the
same object or not, even for those of value types. -- Darren Duncan
