First of all -- awesome, thanks!!! Question 1: the need for the additional typeOf function you added at the end, would that be needed in a future implementation or would that be deduced in the existing reflect.TypeOf in the future?
Question 2: this experience has shown me a bit better that anything is possible but will take some getting used to. Do you think having an "import generics" similar to unsafe as a separate in the actual "library" part of the code would resolve the concerns on user cleanliness? This example I think shows me that if the library writer is careful the end user of the library would have a very minimal impact. As a side note, I started playing with this to understand the other generics long thread going on :-) Thanks again for solving this so quickly!!!
