As you said, it's a personal preference. My own strong preference is
that interface and implementation *should* be physically separated.
The interface is all the client should have to worry about.


Yes, there are tools that can extract an interface specification from
a source file that contains both interface and implementation, and
keeping the interface and the implementation synchronized can be a bit
tedious -- but IMHO it's worth the trouble.
