multi-line guard clauses take too much space.

Compare this

    if (arguments.length < 2) {
        return;
    }

    if (!obj) {
        return;
    }

    if (!isObject(obj)) {
        return;
    }

versus this

    if (arguments.length < 2) {return;}
    if (!obj                ) {return;}
    if (!isObject(obj)      ) {return;}   

The latter one is better, I guess.

We should update the conventions document and go over the source code to reflect the changes.

working on it right now.

[josecapablanca]

did it.

[v0lkan]

closing this one.

[josecapablanca]

re-opening this. -- because conventions document is not yet updated.

plus, I have a bunch of stuff to add to the conventions document too.
