    Transforms an Either into an EitherT, lifted into the specified Applicative.

    Transforms an Either into an EitherT, lifted into the specified Applicative.

    Note: The return type is a FromEitherPartiallyApplied[F], which has an apply method on it, allowing you to call fromEither like this:

    scala> import cats.implicits._
scala> val t: Either[String, Int] = Either.right(3)
scala> EitherT.fromEither[Option](t)
res0: EitherT[Option, String, Int] = EitherT(Some(Right(3)))

    The reason for the indirection is to emulate currying type parameters.
