First Proposed Agenda item for upcoming meeting: Weak references & ephemeron tables

Most of the elements of the table for ES-Harmony are important programmer
conveniences, but are not fundamental enablers for new semantic virtues. For
example, many of these could be implemented by a Harmony-to-ES5 translator.
Similarly, few of these are make or break regarding the possible properties
of (the increasing number of) languages that compile to JavaScript. Such
compiler can work around the absence of many conveniences in their target

Weak references and ephemeron tables are such fundamental enablers. As such,
I'd like us to consider raising their priority for consideration among new
Harmony features. The current proposal is at <>. I'd like
to stimulate discussion on es-discuss and then have it on the agenda for the
upcoming ES committee meeting.

So, what do you think about this proposal?
