This part of my (first) email was about the compatibility namespace
section of the names spec, which has a couple of 'fixme' paragraphs.
The first argues for a way to qualify references explicitly with the
compatibility namespace, and the second makes the case that while
local lexical bindings should be in the compatibility namespace,
unqualified object literal properties should be in the public
namespace. The purpose of these, jointly, is to give people a
reliable way to avoid unintended name shadowing in a with statement.

Right, I get that, and Brendan's point was a good one. I was just
thrown by the fact that I hadn't seen an example of
class A {
var public::count = 10;
}
rather than
class A {
public var count = 10;
}
But if the former is legal (and the grammar suggests that it is), then
there's no inconsistency.
