Re: string_exec()

What I had envisioned includes the ability to modify true top-level code and then re-execute it.
My concern is that you'll effectively be in the middle of the top-level code:
-- this string_exec(...) -- that
If I understand your scheme, it would effectively become:
-- this string_exec(...) -- code generated by string_exec() <-- code begins re-executing here -- that
Is that correct?
That's effectively what happens in the example I posted, though I don't call it string_exec() anymore. However, I envisioned a greater level of control over this however, in that you could control exactly where the code generated is inserted, and also you could separately control where re-execution begins. They don't have to be the current position or even the same place at all.
If the request is allowing self-modifying code, what exactly does that mean? Can a routine be redefined?
Yes.
It seems you can get the same result via routine_id, at a much cheaper cost.

How does one redefine a routine with routine_id() ?
I had envisioned the ability to rewrite the code of a pre-existing routine on the fly, to make it behave completely different.
