/* Virtual Machine
This file contains two virtual machines. First, the old one -- the
one that is currently used, and corresponds to Guile 2.0. It's a
stack machine, meaning that most instructions pop their operands from
the top of the stack, and push results there too.
Following it is the new virtual machine. It's a register machine,
meaning that intructions address their operands by index, and store
results in indexed slots as well. Those slots are on the stack.
It's somewhat confusing to call it a register machine, given that the
values are on the stack. Perhaps it needs a new name.
Anyway, things are in a transitional state. We're going to try to
avoid munging the old VM very much while we flesh out the new one.
We're also going to try to make them interoperable, as much as
possible -- to have the old VM be able to call procedures for the new
VM, and vice versa. This should ease the bootstrapping process. */
