NestedSyntax

Flattens the outer Resource scope with the inner, mirroring the semantics of Resource.flatMap.

This function is useful in cases where some generic combinator (such as GenSpawn.background) explicitly returns a value within a Resource effect, and that generic combinator is itself used within an outer Resource. In this case, it is often desirable to flatten the inner and outer Resource together. flattenK implements this flattening operation with the same semantics as Resource.flatMap.
