Is Option wrapping a value a good pattern?

Question

I recently wrote the following bit of Scala:

val f: File = ... // pretend this file came from somewhere
val foo = toFoo(io.Source.fromFile(f).mkString)
         


        

Answer 1

You add toFoo to String through the pimp my library pattern. Then it becomes:

val foo = Source fromFile f mkString () toFoo
