--- Comment #11 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
read this one again and reviewed the load1 / load2 pseudocode: the rule that SV
is a Sub-PC for-loop has to remain inviolate and fundamental.

attempts to break that inviolate rule result in complications when explaining
the concept, weakening the simplicity.  it is nowhere near worth throwing that

additionally when any given implementation looks at adding SV, the simplicity
of being in between issue and decode is now also violated.  implementors would
be forced to modify the behaviour of designs to comply with the "exceptional
violating behaviour".
