Agreed.
My point was that on embedded devices without floating point and with
minimal memory an implementation
that tries to be compliant will have a tough time because:
- can't implement floating point because no hardware
- can't do a good job at s/w emulation for floating point and
decimal due to memory constraints
For many apps, integer numerics can suffice. But rather than create a
non-compliant extension, I was proposing that the spec allow such
configurations by providing an integer numeric selection pragma.
I hope this clarifies things.
We too are implementing in parallel with the ES4 spec development and
sometimes it is painful as we have to rework our code to track the spec
as it changes. Other times, I hope it is helpful as we get real-world,
hands-on testing of proposed language features before they are set in
concrete.
But then again -- we're not an industry Gorilla and no one will be too
worried if we ship something early ;-)

On the same topic, it seems that Adobe are planning on introducing the
decimal type into the Flash Player before the ES4 spec. is finalised.
They're asking Flash developers at the moment what their requirements
are for "decimal math".
Is the spec. at the point where implementers can start preempting it?
Not quite, but no one is going to preempt -- the early implementors
will have to shift if they want to claim conformance to the final
spec. We've done this in the past in Mozilla and it has been tolerable.
Michael's point seemed to me to be more about divergent long/ulong
semantics and no spec, not early implementations trumped by the one
true spec.
