As unless is a negated form of if, until is really a negated form of while
<![CDATA[
# Compare the following statements. The first is a while loop:
weight = 150
while weight < 200 do
puts "Weight: " + weight.to_s
weight += 5
end
# Here is the same logic expressed with until:
weight = 150
until weight == 200 do
puts "Weight: " + weight.to_s
weight += 5
end
