[ warning, this message is an old dream of mine, no flame please:-) ]

What would be much cooler is pseudo-classes "registered" into the
CSS parser and the rendering engine and based on JavaScript code.
That's something I already proposed in the past, that clearly has
performance issues but that would help a lot some web designers:

@register-pseudoclass my-pseudo-class A_JS_FUNC_IN_DOC_CONTEXT;

where A_JS_FUNC_IN_DOC_CONTEXT is a function taking a DOM element
as unique parameter and returning a boolean. Could be extended
to functional notations through the |arguments| array...
