It would be quite nice to see some more "killer" uses of this new feature that aren't just "we removed some duplication and... saved less than 1% of our loc".

And maybe there are some really compelling ones... I think the only really useful one I see here is `--abs`, which really should just be built-in.

It's not for DRYing/golfing code.

The main use case of functions is that you can parameterize code. This lets you parameterize stylesheets, like set a base font size and primary color, and then derive your whole theme from it, from spacing to secondary border colors to how buttons look when they're hovered.

You can do that with custom properties already. AFAICT functions don't introduce any new abilities on that front (apart from the aforementioned DRY-ing).

abs() exists with cross-browser support:

There are also other non-custom math functions like round() which can be very useful.
