Object initializer for complex object( object inside object)

Hi every one. I found next problem:

let notWork = {
    prop1: {
        [prop2]: 'value'
    }
};

is equal to:

{ prop1: {} }

on the other hand this construction:

let workFine = {
    ['prop1']: {
        ['prop2']: 'value'
    }
};

work fine:

{ prop1: { prop2: 'value' } };

I didn't find any descriptions for complex object in specification.
Can I initialize objects like in first example or this is a bug ?

also I verified this in babel and chrome 44 and this example:

let notWork = {
    prop1: {
        [prop2]: 'value'
    }
};

works as expected:

{ prop1: { prop2: 'value' } };

so this is definitely bug.

That nested case is weird, however, this is essentially a dupe of #2507 and is not something we can address while V8 4.4 is still being maintained upstream. It may be fixed by patching V8 later but that's still to be decided. I suggest you just don't use this feature with versions of Node / io.js that are shipping with V8 4.4.

OK) thank a lot for quick response)
