trailing commas?

This came up while trying to parse automaticRefund.js from the Zoe docs.

The other tweaks seem to be captured in issues already…

• skip import: #8
• skip await / async: #32
• use “” rather than quasi strings (acknowledged TODO in tinyses.js)
• omit trailing commas (this issue)
• omit comments (presumably known issue)

const ast3 = jessie`
const makeContract = harden((zoe, terms) => {
  let count = 0;
  const automaticRefund = harden({
    makeOffer: escrowReceipt => {
      const { offerHandle } = zoe.burnEscrowReceipt(escrowReceipt);
      count += 1;
      zoe.complete(harden([offerHandle]));
      return "The offer was accepted";
    },
    getOffersCount: () => count
  });
  return harden({
    instance: automaticRefund,
    assays: terms.assays
  });
});
`;

I’d prefer to hear from somebody like @erights

Because this syntactic pattern should be encouraged, the Jessie grammar should allow trailing commas. I’m glad it does.
