The automatically imported members are:
- The members of the
java.lang
package - The members of the
scala
package - The members of the
Predef
object
See The scala specification §9.1
Given that only objects (and package objects) can contain methods or values, the only place where standard (with no additional import) implicit values can be found is in Predef
(the scala
package does not seem to have a corresponding package object at the moment).
