feat: Instantiate instances of template instantiation need for self-reference

Browse source 
Formerly, when a self-reference like `self(Tuple<number>)` was encountered,
  but the `Tuple<number>` instance of a `Tuple<T>` implementation for this
  operation had not yet been instantiated, the reference would be fulfilled
  with a call to the catchall implementation for `Tuple`. Now the
  necessary instance is instantiated on the spot and referred to instead.

  This change is used to complete return-type specification for all of the
  Tuple functions.
