   There are two key methods in here.

   There are two key methods in here.

   1) Enter methods such as enterGetterSetter are called from Namer with a tree which may generate further trees such as accessors or implicit wrappers. Some setup is performed. In general this creates symbols and enters them into the scope of the owner.

   2) addDerivedTrees is called from Typer when a Template is typed. It completes the job, returning a list of trees with their symbols set to those created in the enter methods. Those trees then become part of the typed template.

5. #### class PolyTypeCompleter extends Analyzer.TypeCompleter with Analyzer.LockingTypeCompleter with Global.FlagAgnosticCompleter

   A class representing a lazy type with known type parameters.

   A class representing a lazy type with known type parameters. `ctx` is the namer context in which the `owner` is defined.

   Constructing a PolyTypeCompleter for a DefDef creates type skolems for the type parameters and assigns them to the `tparams` trees.

3. #### def +(other: String): String

   Implicit information
     This member is added by an implicit conversion from Namers to any2stringadd[Namers] performed by method any2stringadd in scala.Predef.

9. #### def companionSymbolOf(original: Global.Symbol, ctx: Analyzer.Context): Global.Symbol

   The companion class or companion module of `original`.

   The companion class or companion module of `original`. Calling .companionModule does not work for classes defined inside methods.

   !!! Then why don't we fix companionModule? Does the presence of these methods imply all the places in the compiler calling sym.companionModule are bugs waiting to be reported? If not, why not? When exactly do we need to call this method?

10. #### def deriveAnnotations(initial: List[Global.AnnotationInfo], category: Global.Symbol, keepClean: Boolean): List[Global.AnnotationInfo]

    The annotations amongst those found on the original symbol which should be propagated to this kind of accessor.

    The annotations amongst those found on the original symbol which should be propagated to this kind of accessor.
