Composable EffectHandler

[davidscheutz]

The idea is to make handling side effects reusable where the cases of one effect could be handled by several effect handlers.

Some examples

• displaying an error message
• performing a common API call.

Some questions

• Every EffectHandler is constructed with a specific Effect and returns a specific Effect.Result, how do we map between those two types?
• How to make it clear which case of an effect is handled by which effect handler?
• How to make sure there are no cases left out?

Making one step back, why would this be necessary?

Effect handler can be injected with shared components and using those components comes with little costs...
