FWIW, I believe you!  There's something *inherently* tricky about
maintaining the effect of a stack without using the stack C supplies
implicitly, and from all you've said and what I've learned of your code, it
really isn't the code that's tricky here.  You're making formerly-hidden
connections explicit, which means more stuff is visible, but also means more
power and flexibility *because* "more stuff is visible".

Agree too that this clearly <wink> moves in the direction of making the VM

Ah, if that's how this works, then STOP!  Immediately!  Don't you dare waste
more of our time with this crap <wink>.
