This should do the trick:

def delegate(hash)
   hash.each{ |methods, accessor|
      methods = methods.to_s if
methods.kind_of?(Symbol)
      methods.each{ |method|
         def_instance_delegator(accessor, method)
      }
   }
end

If anyone has a better approach please let me know. 
Otherwise, I'll add some tests for this, then submit
the whole thing as a patch.

Regards,

Dan
