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.

The SASS issue has been brought up some times in the past and what
fantasai is proposing here is just for repeat(), so "grid-template-rows:
(one two) 10px" will be still valid (and problematic for SASS).

IMO it would be a bad idea to have a different syntax just for the
repeat() case, authors will be really confused about whether to use
parentheses or brackets. I don't have a strong opinion on using either,
but I do believe that we should use the same syntax for all the
situations (always brackets or always parentheses).
