[Bug 28798] Make BufferSource more convenient to use

https://www.w3.org/Bugs/Public/show_bug.cgi?id=28798

--- Comment #17 from Boris Zbarsky <bzbarsky@mit.edu> ---
Oh, and the point is that copying at arg conversion time is quite observably
different from copying at entry into prose time.  It's possible to try to add
hacks that avoid it in an implementation (e.g. in my example detect that the
"usage" argument is a primitive and avoid the copy in that case or something),
but relying on implementations doing that is a bit questionable, especially
since it's hard to automate that sort of thing.
