A MultiGet can be constructed in two ways:
  1. MultiGet(Iterable[Get[T]]) -> Tuple[T]
  2. MultiGet(Get[T1]], ...) -> Tuple[T1, T2, ...]

The 1st form is intended for homogenous collections of Gets and emulates an async `for ...` comprehension used to iterate over the collection in parallel and collect the results in a homogenous tuple when all are complete.

The 2nd form supports executing heterogeneous Gets in parallel and collecting them in a heterogeneous tuple when all are complete. Currently up to 10 heterogeneous Gets can be passed while still tracking their output types for type-checking by MyPy and similar type checkers. If more than 10 Gets are passed, type checking will enforce the Gets are homogeneous.
