Support for arguments destructuring

Could be cool to be able to handle functions with arguments destructuring like that :

function({ prop1, "my-prop2": prop2 = 'default', p3 : { sp1 }, ...rest }, arg2) => {
};

That would produce an array like this for example:

[["prop1", "my-prop2", ["p3", ["sp1"]]], "arg2"]

Or event better with more info:

[{
type: object,
properties: [
{name: prop1},
{name: "my-prop2", as: "prop2", default: "default"},
{name: p3, type: object, properties: ["sp1"]}
]
}]

And why not array destructuring support too ?
