Actually, if scratchpads become proper PMC's these ops would be incredibly
useful and common. For example, "@a[0] = %b{1} + $c" might become
add P0["@a";0], P0["%b";"1"], P0["$c"]
This is rather speculative, but if many operations will be on lexicals as
opposed to registers/temporaries, such hoariness might be worth it.
