12: @todo parser4:
13: - cache compiled code from request to request. to do that...
14: -#: make method definitions, @CLASS, @BASE, @USE instructions,
1.88 paf 15: which would be executed afterwards, and actions
16: now performed at compile time would be delayed to run time.
1.106 paf 17: -#: make cache expiration on time and on disk-change of class source
18: -#: in apache use subpools for compiled class storage
19: -#: in iis make up specialized Pool object for that
