A simple, macro-less means of creating accessors from Services. Extend the
companion object with Accessible[ServiceName], then simply call
Companion(_.someMethod), to return a ZIO effect that requires the Service
in its environment.
Example:
trait FooService {
def magicNumber: UIO[Int]
def castSpell(chant: String): UIO[Boolean]
}
object FooService extends Accessible[FooService]
val example: ZIO[Has[FooService], Nothing, Unit] =
for {
int <- FooService(_.magicNumber)
bool <- FooService(_.castSpell("Oogabooga!"))
} yield ()
