Use when you need to recover an Effect only from causes selected by a

Cause.
Details
The filter is applied to the full Cause. When it succeeds, the handler
receives the selected value and the original cause. When it fails, the effect
re-fails with the residual cause returned by the filter.

To run an Effect value, you need a Runtime, which is a type that is
capable of executing Effect values.
