-	- current situation is messy
-	- 2 (3?) different notations for the same thing
-	- unclear when a type assertion is needed
-	- unclear where conversions can be applied

 	- creating a new type (status quo), or only a new type name?
 	- also: declaration type T S; strips methods of S. why/why not?
