Title: Added option for mangling privates in code gen (all members prefixed with a single underscore)

Potentially unsafe, but was an easy add and I know a lot of people who want this, not only does it make the code even smaller (20% in my non-trivial use case) but it's also a nice to have feature if you want to make sure that nobody calls / accesses the stuff :)

Let me know what you think about it.

Best
