Re: [css-variables] Different syntax for variable definition and use

Then, it doesn't make sense to use the 'var' prefix.

use(my-property) and val(x-property) doesn't feel redundant at all.

This is seriously discutable. For example, a "native" property doesn't 
necesarrily exist and can be "invalid", too.

Sample:

    {
        width: use(parent.flex-length, 100%);
        // what if flex-length doesn't exist?;
    }
