Hmmm, I'll byte -- by having joined LOAD_this_STORE_that bytecodes (5 kinds
of loads, 3 kinds of stores, that's 15 new bytecodes) and a few
call-and-poptop
ones?  And a peephole optimizer to change the bytecode stream coming from
the current compiler to one using the new bytecodes (and making a few more
minor opts while he's at it)...?

Or am I missing something obvious...?  'cause I don't think that would
delete
90% of the datamovement instructions -- maybe 30 to 40% or so...?
