class CtxLazy [ T ]
extends Object

Utility class for lazy values whose evaluation depends on a context. This should be used whenever the evaluation of a lazy expression depends on some context, but the value can be re-used afterwards with a different context.

A typical use case is a lazy val in a phase object which exists once per root context where the expression intiializing the lazy val depends only on the root context, but not any changes afterwards.
