**Use-case: Matrix and Convolutions**
* **Horizontal-First**: (aka standard Cray Vectors) walk
- through **elements** first before moving to next instruction
+ through **elements** first before moving to next **instruction**
* **Vertical-First**: walk through **instructions** before
- moving to next element. Currently managed by `svstep`,
- ZOLC may be deployed to manage the stepping.

Imagine a large Matrix scenario, with several values close to zero that
could be skipped: no need to include zero-multiplications, but a
