/**
@todo parser4:
- cache compiled code from request to request. to do that...
-#: make method definitions, @CLASS, @BASE, @USE instructions,
which would be executed afterwards, and actions
now performed at compile time would be delayed to run time.
-#: make cache expiration on time and on disk-change of class source
-#: in apache use subpools for compiled class storage
-#: in iis make up specialized Pool object for that
