Could not agree more but I am desperately looking for a way to replace this
which I use *very* often

class Mine
     eval <<-EOS
     def #{name}( value, &block )
           do_something( &block ) if block_given?
    end
   EOS
end
I'd *love* to do it with define_method, but I do not get around the "&block=
"
parameter.

Anybody help?

Thx
Robert
