If you like classes i ve made some

If you like classes, i've made some utilities that leverage abstract classes to fold service interface (class type), service tag (class static side), and having a place to put base implementations if you like (class instance and constructor), into one definition (abstract class):
https://github.com/effect-ts-app/libs/blob/main/packages/infra/_src/services/Emailer/service.ts#L12
you don't have to inherit from the class unless you want to:
https://github.com/effect-ts-app/libs/blob/main/packages/infra/_src/services/Emailer/fake.ts#L4
https://github.com/effect-ts-app/libs/blob/main/packages/infra/_src/services/Emailer/Sendgrid.ts#L7

so it saves you from defining interface and tag separately and gives you a place to share base implementation.
in my case, it also saves you from defining the

.Ops

.Ops

side of the tsplus type (const + interface), but that's just for tsplus junkies as it's defined as companion on the class.
~Ill try to update it soon to the newest versions of effect, and we can start using

TagClass<SVC>

TagClass<SVC>

instead of

TagClass<Tag<SVC>>

TagClass<Tag<SVC>>

, that was just a workaround for some unique symbol issues.~
