The problem with this particular proposal is that it kind of throws
out the fact that Sizzle works right to left on the selector. We
currently evaluate the left-hand-side of the selector first ONLY if
there's an #id at the beginning. So we could, theoretically, get your
proposal to work but ONLY if the selector began with an ID - and that
seems a bit weird.
I'd be open to an alternative proposal: Simply removing the need to
have to do .contents() before calling .find(), this way you could do:
$("iframe").find("body") or $("body", "iframe")
Does this work?
