hi,
In ruby we can delegate some method. by example:
---- Ruby ----
class MineArray
   include Forwardable
   def_delegators: @array, :[], :[]=, :each_with_index, :length
   def initialize( array )
     @array = array
   end
end
-------------

this code delegate opIndexAssign opIndex, length ... attribute to his
member.

This save time, bug and line. You do not to have to write a code as:
void opIndexAssign( size_t index, T item){
        array[index] = item;
}

thanks

I miss the question ^^

can w do same in D ?

thanks

I would say "yes", but not with the same pretty syntax. Something like this:

class MineArray
{
    mixin delegates!(array, "opIndexAssign", "opIndex");
}

Just implement "delegates" to generate the given functions and forward 
them to "array".
