able to store `calc(20px / 1s)` into a variable and then use that in
multiplication and division to translate between two otherwise unrelated
units.

We don't have this yet; unit algebra means you can run into division by
zero that can't be detected until computed or used value time, so it's too
late to treat as a syntax error.

We plan to revisit this in the next level, though.
