&& isn't explained

[SomMeri]

Moved from less.js issue less/less.js#1652 Original description:

Until recently I didn't knew about && as a placeholder for selectors. It seems that this feature isn't documented anywhere.

A few ideas for more "advanced &" examples:

// protozoa:
na { ba&&   {._}}
co { &&nut  {._}}
cu { &&mber {._}}
ti { pe&&on, &re { &, re& {._}}}

// don't repeat yourself:
.me {
    &&, & &, && &, & &&, &&&& {._}
}

// robotics:
0, 1 {
    &&&& {._}
}

// ._
._() {D:-}

lol awesome

Btw., what would be a meaningful "&" feature title? There're a few features sub-sections that I'm planning to join into one category but it looks like there's no generally accepted name for this feature.
So far I found: "Appender", "&", "Ampersand", "Self Selector". There's also "Parent Selector" (but there it seems to be dedicated exclusively to "backward & usage": .ie & {}).

I used appender so far, but I like Parent Selector even more - it is more descriptive. Outer selected could be used to, but I'm not sure how much it is English.

Or even parents selector (note plural)

Ok, so I guess I'll stick to "Parent(s) Selector" for the moment. Now I have actually remembered that initially Parent-Selectors.md contained more info about "&" in general but then most of this info was moved into nested.md since almost every example there was the same. Now when contents of nested.md repeat almost everything said in "Overview:Nested Rules" (thus nested.md is not even published in features) I guess I need to move anything about "&" back to Parent-Selectors.md. 👯

Closing as "it is now (at least partially).
