Wrap method vs chain method

Imagine we have the following:

sealed trait Foo

case class FullFoo[A](foo: A) extends Foo

case object EmptyFoo extends Foo

and

def liftToFoo[A](opt: Option[A]): Foo = 

  opt.map(a => FullFoo(a)).getOrElse(EmptyFoo)

We can easily do:

liftToFoo(Some(123)) // FullFoo(123)

liftToFoo(None)      // EmptyFoo

But I'm curious if there's some "chainable" way to call this (rather than wrapping the method like above):

Some(123).someFunction(liftToFoo)  // FullFoo(123)

I'm trying to avoid using an implicit class to achieve this style. Curious if there's something I can use already.

Not exactly what you're looking for but perhaps a little closer than what you've got.

Some(123).fold(EmptyFoo:Foo)(FullFoo(_))

A) Yeah, but you said you were "trying to avoid an implicit class". B) Success()? Failure()? That's a Try, not a Foo.

Re: implicits, yeah totally! Lol I hacked together this "Foo" example, but was really thinking of applying it with a Try :P You caught me in some Frankenstein copy/paste :)
