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.
The annotations amongst those found on the original symbol which should be propagated to this kind of accessor.
Logic related to method synthesis which involves cooperation between Namer and Typer.
