    The phase performs the following transformations (more or less...):

    The phase performs the following transformations (more or less...):

    (1) An class which is not an interface and is not static gets an outer accessor (@see outerDefs). (1a) A class which is not a trait gets an outer field.

    (4) A constructor of a non-trait inner class gets an outer parameter.

    (5) A reference C.this where C refers to an outer class is replaced by a selection this.$outer$$C1 ... .$outer$$Cn (@see outerPath)

    (7) A call to a constructor Q.(args) or Q.$init$(args) where Q != this and the constructor belongs to a non-static class is augmented by an outer argument. E.g. Q.(OUTER, args) where OUTER is the qualifier corresponding to the singleton type Q.

    (8) A call to a constructor this.(args) in a secondary constructor is augmented to this.(OUTER, args) where OUTER is the last parameter of the secondary constructor.

    (9) Remove private modifier from class members M that are accessed from an inner class.

    (10) Remove protected modifier from class members M that are accessed without a super qualifier accessed from an inner class or trait.

    (11) Remove private and protected modifiers from type symbols

    Note: The whole transform is run in phase explicitOuter.next.

    TODO: Make this doc reflect what's actually going on. Some of the deviations are motivated by separate compilation (name mangling based on usage is inherently unstable). Now that traits are compiled 1:1 to interfaces, they can have private members, so there's also less need to make trait members non-private (they still may need to be implemented in subclasses, though we could make those protected...).

  45. def transformInfo(sym: Global.Symbol, tp: Global.Type): Global.Type

    The type transformation method:

    The type transformation method:

    - Add an outer parameter to the formal parameters of a constructor in an inner non-trait class;

    - Add a protected $outer field to an inner class which is not a trait.

    -

    Add an outer accessor $outer$$C to every inner class with fully qualified name C that is not an interface. The outer accessor is abstract for traits, concrete for other classes.

    3a. Also add overriding accessor defs to every class that inherits mixin classes with outer accessor defs (unless the superclass already inherits the same mixin).

    - Make all super accessors and modules in traits non-private, mangling their names.

    - Remove protected flag from all members of traits.

    Note: this transformInfo need not be reflected as the JVM reflection already elides outer pointers.
