    The expression after the 'case' keyword is the right hand side of the === expression, and the expression after the 'when' keyword is on the left hand side of the expression. So, the method that is being called is String.===, not A.===.

    A quick approa...

    class Revcomp
    def initialize(obj)
    @obj = obj
    end

    def ===(other)
    other === @obj
    end

    def self.rev(obj)
    Revcomp.new(obj)
    end
    end

    class Test
    def ===(other)
    puts "here"
    end
    end

    Is there a way to override operator overloading in Ruby?To my knowledge, Ruby doesn't have true operators, they are all methods which are invoked on the LHS of the expression, passing in the RHS of the expression. So, really, you could override any "operator" you want in your classes to perform whatever the heck you want (analogous to operator overloading in C++).

    What are operators in Ruby?In Ruby, operators such as +, are defined as methods on the class. Literals define their methods within the lower level, C language. String class, for example. Ruby objects can define or overload their own implementation for most operators. Here is an example: self. concat ( str ). concat ( "another string" ) end end foobar = Foo. new ( "test " )
