As far as I know, the plan is still to do [ArrayClass] for the results
of el.queryAll(), regardless of whether .qSA() has compat problems.
You just gave basically the entire reason - the existing "slice it
like an array" hack is *total bullshit*, and everyone hates it.

(I add a "function queryAll(sel) { return
Array.prototype.slice.call(document.querySelectorAll(sel)); }" to my
doc any time I'm doing any DOM manipulation, because I hate it so
