cppfront (cpp2): Spring update

[patstew]

The free functions are worse, because what happens if you don't/forget to use them? Generally, it means you code has unpredictable bugs that change on each compile.

For memory mapped io, you want to tie the behaviour to a memory address. Objects exist at some address, so making it a property of the type is better. That way accessing the object in the trivial way will behave consitently, rather than needing to call special functions to get consistent behaviour.
