Nice. I would guess many of us would have versions of this, it would be 
good to formalise it so that it could deal with :
- namespaces, you might want your unexported functions to be separate 
from your exported functions. It looks like your function loads 
everything into .GlobalEnv
- S4 objects, what would happen if you re-source the definition of an S4 
class and continue to manage objects created before the resourcing
