Sure. I'm suggesting so as to simplify that on failures the retry would
always restarts from the beginning of the script by resetting everything,
indeed including the conditional stack, the random generator state, the
variable values, and so on.
This mean enforcing somehow one script is one transaction.
If the user does not do that, it would be their decision and the result
becomes unpredictable on errors (eg some sub-transactions could be
executed more than once).
Then if more is needed, that could be for another patch.
