Problem is simple:
I want to know if an integer is within the range of x and y. However, I 
don't automatically know which of x & y is the largest.

Ruby accepts ranges like (5..2), although there seems to be no real use 
for them.

Anyway, is it possible to automatically create a "valid range", or is 
this kind of solution the best one?

range = x < y ? (x..y) : (y..x)


Best regards,
