This namespace check already saved me a lot of time. I found an issue in 
our latest code (not submitted for review yet) with a new functionality 
added to the wrong module and without the proper abstraction required...
Really nice tool, I can already see how useful it will be for on-going 
code partitioning (SOF multi-client work and virtualization support).
