Pixie Scheme's stack or continuation, or any of the other data that would be required to pick up in the middle of an executing program. Thus a saved world contains only a topΓÇôlevel environment: Once that environment is reloaded, you must evaluate an expression manually to get things to start happening.
In any case, a world load does a reset immediately after completing the load. You will then be back at topΓÇôlevel, even if the world was saved from within a program, or even if you called "e::load-world!" from within an executing program.
