The docs have a bit more on it [1]. The $$ is really just a dollar quoted string[2], you can use any sort of string in there, but dollar quoting just makes it a lot easier to read.

On your other question, not right now, but if it's something you want, file a github issue, it's something we've thought a bit about and it gets hairy pretty quickly, but also increases the power of these things dramatically. We'll probably do something with it, but it may be a little while and we may let this stuff bake for a bit first...
