Object literal treatment under ADVANCED_OPTIMIZATION is not clear

[gonzojive]

It's unclear how object literals are treated under ADVANCED_OPTIMIZATION. The tutorial page that explains ADVANCED_OPTIMIZATION is incomplete.

I believe the following code does not preserve the 'preserveMe' property:

var x = {preserveMe: false};

However, this code does:

var x = {'preserveMe': false};

Please clarify the compilation semantics in the docs.

yes, quoted object literal keys must be quoted to be preserved if there isn't not an matching extern declarations.

The example in the section "Inconsistent Property Names" uses an object literal.
