Object destructuring inside the rest parameter

[peey]

Babel is unable to parse ({ x, ...{ y, z } } = o). It's valid according to the spec.

Input Code / Babylon Configuration

babylon.parseExpression("{ x, ...{y, z} } = o", {"plugins":["objectRestSpread"]});

Expected Behavior

It should parse correctly to be transformed into a functionally equivalent code of the following:

x = o.x
rest = _objectWithoutProperties(o, ["x"])
y = rest.y
z = rest.z

Current Behavior

This error is thrown

SyntaxError: Invalid left-hand side in rest property (1:8)`
