Cleanliness

If there are no python files in a directory, we don't need to add an init.py file to that directory. Sure, they don't hurt, but having them where they aren't needed isn't very tidy and might be confusing.

Speaking of confusing, lets test javascript

function assert(condition, message) {
    if (!condition) {
        message = message || "Assertion failed";
        throw new Error(message);
    }
}

assert([]+[]=="", "very sensible, adding arrays is a string")
assert({}+[]==0, "of course adding a dict to an array is 0")
