Hi, I’d like that we consider removing the subject indicator and adding an :has() pseudo-class (described below) instead. Reasons include: * "!" suggests a "boolean negation" meaning that the subject indicator doesn’t have. * :has() already exists in hitchjs and (in limited form) in jQuery. * IMO having a name is preferable to assigning arbitrary meaning to ASCII characters, and worth the verbosity. * This resolves the issue of whether to append or prepend the indicator. * Assuming :matches() exists, I believe they’re equal in power. * The performance concerns are the same. :has() ------ :has(), is a functional pseudo-class taking a list of <a>relative selectors</a> as its argument. It represents an element such that its argument represents anything with the element as the <a>scoping root</a>. Example: div:has(p) represents a <div> element that has at least one <p> descendant element. Example: div:has(> p) represents a <div> element that has at least one <p> child element. :has() is not allowed in the <a>fast profile</a>. The specificity of :has() is calculated like :matches(). -- Simon Sapin
