           Summary: Converting an ECMAScript value to a dictionary; use
                    [[GetOwnProperty]] or [[Get]]?

Should we use [[GetOwnProperty]] or [[Get]] for checking the dictionary for a
member?


Asking because with accessors on prototypes of Event objects, can I pass an
event object instance in the dictionary parameter for an event constructor and
have it work?

In http://heycam.github.io/webidl/#es-dictionary, is ambiguously says:

"For each dictionary member member declared on dictionary, in order"

It reads (to me) like "on" is a [[GetOwnProperty]], but perhaps it should be
[[Get]]??
