@DevAndArtist No. Before I created this thread, I discussed the proposal of the thread with my colleague and during the discussion I noticed that variadic generics can be broken down into small steps.
It was just an idea and I was not sure if it was a good approach. It is also composed of independent parts from variadic generics. So I created this thread as a pitch to gather opinions about the idea of this approach, not for concrete syntax and implementation about variadic generics.
Maybe I should have referred to it and linked to the thread. Sorry.
