• cannot produce a new type parameter in a receiver function (a method)
  • e.g. this won't work: func (iter Iterator[T]) ChunkSlice(size int) Iterator[[]T] ([]T is a new type parameter)
• type inference sometimes is broken (see the unit tests where I have to add the variable type hint)
• cannot define type alias inside function (will treat the type parameter as index) - it is not a critical issue but makes the code cumbersome
• Go doesn't have first class tuple and pair types: Tuple[T...], or Pair[T, P]
• no variadic type parameter support (or I don't know?)
