NodeJS code should not be namespaced (and is currently not strict-mode compliant)

Code generated for NodeJS, whether with a js namespace specified or not, seems to fail strict mode. Specifically, it doesn't always generate "var" when needed. This might not sound like a big issue but it's quite a pain to deal with...

It is standard nowadays to enable strict mode for Javascript code (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode). And babel, which is one of most popular ES6 => ES5 transpilers, while does not force strict mode, does seem to break when you don't use "var".

I think the best solution here is really to just stop using namespaces in node code. Every type will be declared with "var", and if exported, also assigned to "module.exports".

I don't believe namespaces currently generated in the node code is directly used anywhere or is even accessible outside the file?
