Multi-methods or multiple-dispatch would be more correct in the
context of a language like ruby.

I found it quite brave of Daniel to make that proposal. :-)

I personally would like to see some sort of annotations that could be
used for this.

class A

    S = "FOO"

    @pre x.respond_to?(:*)
    @post result.is_a?(String)
    def fooer(x)
        S * x
    end

end

Such annotations would leave it up to the users to use them for
whatever they like and process them in a customizable way or to simply
ignore them. The only (soft) guideline would have to be that the code
should still be functional if they were totally ignored.
