Is there any proper reason why in CSS `calc(2em/1em)` won't give you `1`? Would be so useful for getting proportions with the unit canceled.

@kizmarh It makes dealing with divide-by-zero easier (hard to tell if (16px-1em) is 0). But plan is to allow it in next level.

@davidbaron no no, right now I’m talking about the handling of the _same_ unit values, and specifically about the division of them.

@kizmarh I know, but it's a problem once you introduce units on the bottom of fractions. Also, different units seem more useful.

@davidbaron example: `transform: scale(calc(2em/1em))` should be allowed and be equal to `transform: scale(2)`.
