| @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 | |
