The Use of LazyArg<Effect> in the `orElse` Function

why does

orElse

orElse

take a

LazyArg<Effect>

LazyArg<Effect>

as the fallback, instead of just an

Effect

Effect

?

I am looking at it like

flatMap

flatMap

zipRight

zipRight

, one takes the result of the previous effect, so requires a function. Where the other is independent so it does not.

Compare that to

catchAll

catchAll

orElse

orElse

. Catch all of course requires a function to get the error from the previous effect, but why is the

orElse

orElse

fallback effect lazy?
