46: - cache compiled code from request to request. to do that...
47: -#: make method definitions, @CLASS, @BASE, @USE instructions,
48: which would be executed afterwards, and actions
49: now performed at compile time would be delayed to run time.
50: -#: make cache expiration on time and on disk-change of class source
