Re: [csswg-drafts] [css-values-5][various] Better handling of arguments with commas (#9539) from Kevin Babbitt via GitHub on 2024-01-30 (public-css-archive@w3.org from January 2024)

I lean towards a new generic function as well. If `;` were allowed as a function argument separator, I could see problems stemming from the inability to put `;` in a variable value. I couldn't come up with a realistic example, but here's a contrived one:

```
.foo { background-image: mix(50%; var(--mix-or-toggle-me)); }

.bar { background-image: toggle(var(--mix-or-toggle-me)); }

:root {
  --bg-a: url(1.png), url(2.png);
  --bg-b: url(3.png), url(4.png);
  --mix-or-toggle-me: var(--bg-a);var(--bg-b); /* oops */
}
```
