What do you think "===" means? Hint: it's not the same as "==", or
"<<". And it doesn't mean "is equals to". Obviously (1..5) does not
equal 3.

The #=== method is called in case statements, and it is up to each
class to define something reasonable.

case 3
  when 1..5
    puts "(1..5) === 3 means 3 is inside the range."
  when Integer
    puts "Integer === 3 means that 3 is a sort of Integer"
end
