> Currently, {{filter}} support is limited to a set of types, and these types cannot be arbitrarily nested. This hints at a fundamental limitation of the design, that is currently typed (in rust's sense).
> However, this operation is fundamentally un-typed: we do not require knowing type information to filter an array.
> This issue tracks the development of an abstraction to support these operations for arbitrary types.
