And using David's suggestion in another post and adding a a twist we
lose even more!!!

puts "x " + case
when x < 0; "< 0"
when x < 1; "in interval [0,1)"
when x < 2; "in interval [1,2)"
else        ">= 2"
end

Although I kind of think I might have gone a little too far and lost
some readability in my quest to eliminate duplication. Fore!!!!
