Re: [csswg-drafts] [css-values] Trigonometric functions (#2331)

Will commas (`,`) or slashes (`/`) be used as the argument delimiter in these functions?

More recently, I’ve seen slashes (`/`) used as the “official” argument delimiter — like with background and grid declarations or modern color functions — while commas have been used to separate values from fallbacks — like with `var()`. However, slashes (`/`) might be confused for division symbols in math functions.

With a slash:
```css
width: pow(2% / 4);

/* becomes */

width: 16%;
```

With a comma:
```css
width: pow(2%, 4);

/* becomes */

width: 16%;
```

Neither feel especially wrong to me, but it looks a little funny when I add some inner calc.


With a slash:
```css
width: pow(calc(2% / 4) / 4);

/* becomes */

width: 0.0625%;
```

With a comma:
```css
width: pow(calc(2% / 4), 4);

/* becomes */

width: 0.0625%;
```
