I saw the meeting minutes, and got a debrief from Allen yesterday.
I'm still unclear on how to proceed with Decimal, even if the new
target is Harmony.
Waldemar's issues were raised and responded to prior to Kona:

Did this address Waldemar's other message?

I also don't see a reply to David-Sarah Hopwood's message:

What are we left with relative to the the following output from the
code that I wrote?
http://intertwingly.net/stories/2008/09/20/estest.html
Looks like we may need Waldemar to comment or elaborate on his last
post (first link above).
Relative to that output, I've heard two issues.
The first was "no user visible cohorts". The issue is Waldemar's
insistence that ES is irretrievably broken if array lookup for
x[1.10m] respects the trailing zero. IIRC, Brendan's position was a
more pragmatic one, namely that "small" integers (like, say, up to
10**20th) are the only values for which toString must avoid both
exponential notation and trailing zeros, other values shouldn't get in
the way of "doing the right thing". That would have been fine, but
unfortunately he couldn't make the meeting (something I definitely
understand). Mike and I weren't then, and still aren't happy about
conceding to Waldemar's position on this one, but at Redmond we did
with the understanding that with that concession, Decimal was "in".
This Redmond-meeting result did sound like a breakthrough in any
event. Was it memorialized with spec changes?
The second was the duplication between "Math.min" and "Decimal.min".
I was operating under the "if it ain't broken, don't fix it"
guidelines. To date, Math.min *always* returns a Number, never an
Object. Waldemar apparently feels that people will call the wrong
function. To me, this is a "you say N-EEE-THER, I say N-EYE-THER"
issue. If the consensus is that Math.min should be changed and
Decimal.min should be removed, that's a pretty quick fix.
This doesn't seem like a big problem, by itself.
So now the question is: where are we now?
The two general kinds of problems from the Kona meeting were:
1. Spec bugs, not just typos but material ones that couldn't be fixed
by that meeting, which was the deadline for major additions to ES3.1
not already in the spec.
2. Future-proofing arguments including: do we need Decimal wrappers
for decimal primitives. I know we've been over this before, but it
still is an open issue in TC39.
I'd appreciate Waldemar's comments; and those of other TC39ers too, of
course.
