9. def fromOption[F[_]]: FromOptionPartiallyApplied[F]

   

   Transforms an Option into an OptionT, lifted into the specified Applicative.

   Transforms an Option into an OptionT, lifted into the specified Applicative.

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

   scala> import cats.std.list._
   scala> val o: Option[Int] = Some(2)
   scala> OptionT.fromOption[List](o)
   res0: OptionT[List, Int] = OptionT(List(Some(2)))

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