Another feature that doesn't seem to be under consideration is a way to 
target the first rather than the second of two adjacent siblings 
(analogous to the + combinator but backwards).

The simplest situation I can think of where this would be useful is to 
remove or adjust vertical spacing when a paragraph is followed by a list. 

If vertical spacing is expressed via margin-top I can write:
p + ul {margin-top: 0}

But what if I want to use margin-bottom instead or as well? I'd like to be 
able to specify something like:

p:followed-by li {margin-bottom: 0}


p  ul {margin-bottom: 0}

where the proposed combinator between the p and the ul is the division 
sign (U+00F7).
