Scalaz library import technique reasoning

Question

Do any of you know why examples from Scalaz always use this import technique:

import scalaz._
import Scalaz._

rather than:

import scalaz.Scalaz._

? I'm trying to understand what the reasoning behind the preference is.

Thanks!

Answer 1

I believe it's because import scalaz._; import Scalaz._ imports all members from the scalaz package and from the scalaz.Scalaz object.

If you will just import import scalaz.Scalaz._, then you only import members from the scalaz.Scalaz object.
