There was a problem hiding this comment.
@odersky, I'm curious why getting a signature of a DefDef requires creating a new Typer\Namer, while ValDefs and TypeDefs are fine using existing one?

When the symbol completer runs, it may create a new Typer instance. But if the current typer is a derived typer the completer won't create an instance of the derived type. This change adds a method "newLikeThis" to the Typer class that can be overridden by derived typers.
