--- Comment #10 from Anne <annevk@annevk.nl> ---
Here's a strawman:

1. BufferSource (and what it expands to) copies by default. This is safe and
the common case. It gives the specification algorithm to a byte sequence. IDL
handles all exceptional cases.
2. [Detach] BufferSource detaches the buffer source and gives the specification
algorithm access to a byte sequence. This is useful for Web Audio, maybe
elsewhere. IDL handles all exceptional cases.
3. [UnsafeReference] BufferSource gives the specification algorithm to the
JavaScript object. Handle with care. postMessage() and friends will need this.
IDL only performs its normal checks.
