Effect.fn pipeables vs named curried Effect.fn for spans

const sendEmail = (request: SendEmailRequest) =>
  Effect.gen(function* () {
    // ...
  }).pipe(
    Effect.withSpan("EmailService.sendEmail", {
      attributes: {
        "email.to": request.to,
        "email.from": request.from
      }
    })
  )

const sendEmail = Effect.fn(
  function* (request: SendEmailRequest) {
    // ...
  },
  (effect, request) =>
    Effect.withSpan(effect, "EmailService.sendEmail", {
      attributes: {
        "email.to": request.to,
        "email.from": request.from
      }
    })
)
