Question, 'any' type compatible type to Object type.

[NN---]

I want a type similar to 'any' but can be initialized only with Object compatible type.
Is it possible to do this ?

var a : {any};

a.x = 1; // OK
a["x"] = 1; // OK
a = {}; // OK
a = 1; // Error !

The workaround is to use indexer, but then syntax 'a.x' doesn't work.

var a: {[key: string]: any;};

a = 1; // Error

I think this is roughly a duplicate of the request here #1809.

Yes, exactly what I want.
Thanks
