Actually, CSS variables are quite variable in terms of their values can be specified once and then overrided/altered. However terminology is not key factor here, what's more important is how variables are used on syntax level.

We could just use different functions: `var(example)` to access value of variable that has been declared via `var-example` property, and something like `prop(propName)` to access properties by their full names (without stripping any prefixes like `var-`). For example, we have such special-casing for `data-`-prefixed attributes with `element.dataset` DOM-object compared with accessing regular attributes via `element.getAttribute()` method.
