aMap.readOnlyView() shares state, right?

[dckc]

I don't see much about how readOnlyView on Map works.

proposal-readonly-collections/README.md

Line 52 in 89dc726

readOnlyView() :ReadOnlyMap(); // necessarily fresh

Which part of the spec tells us that...

const m  = new Map();
const ro = m.readOnlyView();
m.set('a', 1);
ro.get('a')

... completes with 1?

yes
