Question

What does this package naming structure accomplish in a Scala file?

package myco.group.component
package foo
package bar

Answer 1

It’s the same as:

package myco.group.component.foo.bar

import mco.group.component._
import mco.group.component.foo._
import mco.group.component.foo.bar._

Also the same as:

package myco.group.component {
    package foo {
        package bar {
        ...
        }
    }
}
