... and can you take the compiled executing code and continue
to develop it interactively? (For which I do not mean
returning to a source file, editing it and then recompiling)

My thinking is that for any interactive program, there has to be
some form of tokenisation to represent the source program, so
why should not those tokens be the carefully-chosen unambiguous
machine code instructions that execute the code?

I am sure that this is not an original idea and that it has been
done many times over the years what with everyman and his
aunts, uncles and family pets all having a go at computer programming,
but it is an idea with which I dabbled back in 1986 and that now I
have the spare brain capacity to continue with!

ie, considerable exhaustion resulted then with intensive programming
in the daily round of my job and then attempting even more programming
in the evenings.

1986? Half a lifetime ago, I being 70 next month!   :-)
