I love the use of UnboundMethod. I'm going to have to remember that one.
[:<, :>, :<=, :>=].each do |operator|
[Float, Fixnum, Comparable].each do |klass|
klass.class_eval {
alias_method("__#{operator}__", operator)
define_method(operator) do |operand|
send("__#{operator}__", operand) and operand
end
}
end
FalseClass.send(:define_method, operator) { false }
end
(1..10).each do |x|
case
when x < 3
puts "#{x} is quite low"
when 3 <= x < 6
puts "#{x} is quite all right"
when 6 <= x < 10
puts "#{x} is quite fine"
when 10 <= x
puts "#{x} is quite high"
end
end
Tried to port some Perl code, but I'm not quite sure if it's Rubyish enough…
