Subject: How to pass a given block to a subroutine

Hello ,

I have a method 'foo' that takes a block, but the yield should
be done in a subroutine.

======================================================
class Example

        def foo (*args)
            subroutine *args
        end
        
        def subroutine *arg
            yield *arg # want to call the block given to foo
        end

end

a = Example.new
a.foo(10,20) { |a,b| print "#{a + b}\n" }
=======================================================

If you ask why i want to do this:
i have to replace an existing subroutine with my own version, that
does something before yield is called. So i renamed the method
and must now find a way to call it from my version.
