-  @spec stream(t(), Enumerable.t()) :: Enumerable.t()

-  Produces a `Stream` that filters out and manipulates elements of an `enumerable`.
-
-  Elements of the `enumerable` that match one of the `spec`'s clauses
-  will transformed as instructed.
-  Elements that do not match will be filtered out of the result.

-  Always returns a lazy `Stream` enumerable.

-  ## Note
-
-  This function wraps the `enumerable` in a lazy `Stream`.
-  If the `enumerable` is something you can safely convert
-  to a list without going on forever or loading too much into memory,
-  consider using `run/2` instead, as it is more efficient.
