[Shin The Gin] - Wouldn't it be nice for an interative environment, to save it's complete state into a file and restore it later?

How would one do it with Tcl?

I know [Tcl] has a lot of introspection capabilities, but do they enable a complete saving of states?

[RS]: See [serializing] and [Dumping interpreter state]

[NEM]: See also [continuation], depending on what is meant by interpreter state.
