Where is the proof that these new features make you more productive ?

I created a code generator that creates boilerplate classes and associated unit test cases.
All with in essence D7 style code, ready to go.
I don't think that generics would do anything to improve the situation.
I could gain a few lines because I could use a generic list&enumerator, 
but that's it.

To improve this situation I advocate NOT yet to spend effort on new
language modes, but first get the Delphi compatibility to a decent level.
I think that this will do more to help productivity than new modes.

After that, we can still see about new modes. I'm not arguing about that.
