One obvious conflict many seem to be overlooking is the conflict with
the use of $ in css preprocessors.
IMO, the proposal for variables is great, but it is quite different from
what is currently found in preprocessors like sass. Sass also offers
mixins.
In sass, both variables and mixins use $ as part of their syntax. If
we start allowing $ in css, sass probably needs to be changed to use
something else, and I don't think this is desirable.
Compatibility with sass as such isn't an important goal for the CSSWG,
but it is a good example of why changes to the core grammar are not
desirable, as they make break unsuspecting tools in the wild that
rely (maybe unknowingly) on the core grammar staying what it is.
