final def &![Fx2 <: Signature](fx2: Fx2): Combine2[Effect.this.type, fx2.type]

API for defining custom handlers.

API for defining custom handlers.

Combines with another Effect instance, for the purpose of sharing an Interpreter.

Example of application: implement RWS-alike handler for Reader &! Writer &! State composition of effects.
