Pollutes global scope with `Module`

[davidyuk]

Running hash defines a global variable Module with some internal stuff. Probably this comes from emscripten but would be better to avoid this, because of:

• possible collision that may happen (also may be fixed by changing Module to something more specific)
• to don't expose library internals without reason
• in general, to don't define/change global variables should be a good practice

I don't think it will be possible to solve this without changing how it works inside emscripten. Not closing for visibility, no action will be taken.

Actually, I'm wrong, it's possible to change it: https://stackoverflow.com/questions/30152622/changing-the-default-namespace-module-in-emscripten
