FWIW, there's at least some non-subjective reason to prefer brackets, because parentheses conflict with the SASS/LESS value-computation syntax. I would actually be happy to use "width: (100% - 125px)" instead of "width: calc(100% - 125px)" in my stylesheets, especially if (in some hypothetic future) we expand the calc syntax to match things we can do in Media Queries L4. Anyway, even without this, I think naming a line isn't an essential feature enough to endorse the responsibility of closing the door to some general-purpose grouping feature in css, whichever it may be.

Given there's no shipped implementation of css grid and I've yet to see a good reason to prefer parentheses, I would welcome the change.
