It’s only the ECMAScript language binding that uses the ES ToString
etc.
algorithms, so I think it would be fine to define in the ES language
binding section that exceptions thrown when converting an IDL value to
an ECMAScript value or vice versa will propagate to whatever invoked
that conversion.
Oh of course, completely forgot that there's actually a set of
bindings sections :D
Until (unless) somebody writes up a Web IDL language binding for
Objective-C, the best you can hope for is for Obj-C implementations to
do something “sensible”.
Effectively this is what WebKit does to generate it's ES and Obj-C
bindings.
