**without modifying the Scalar instructions**. A small conceptual
"cheat" was therefore needed. The Immediate (D) is in some Modes
multiplied by the element index, which gives us element-strided.
-For unit-strided the width of the operation (`ld`, 8 byte) is taken
-as the multiplier. Modifications to support this

"cheat" on top of pre-existing Scalar HDL (and Simulators)
have both turned out to be minimal.[^mul]
