That's why I mentioned infinite ranges. An infinite range is *defined*
as a range where empty is implemented as
enum bool empty = false;
isInfinite(Range) tests whether this is the case, which it wouldn't be
able to do if empty() was a function.
Which makes me think: what about a range that can but may not
necessarily be infinite depending on runtime parameters? For instance,
you could have a range returning a rational number as decimal digits:
some will be infinite and others will be finite depending on the
rational number (like 1/3 vs. 1/4). You can't express that with an enum.
I guess you could fix that by overloading isInfinite for your specific
range type though.
