Is it possible to clone or save/restore engine state?

[KarolKolenda]

I've got relatively long initial code and then I use the engine to execute a single statement which can affect engine state. I would like to speed things up by not re-executing initial code all the time. Would it be possible to:
a) quickly clone the instance of engine with it entire state or
b) save and restore quickly engine state?

Many thanks,
Karol

It would be great if Engine would implement ICloneable

I'm wokring on a PR #788 that should serve this purpose by allowing a temporary context to run commands in that can then be cleaned.
