looks like the current implementation recursively checks the 
dependencies regardless of whether they inherit their parents or not.
in my opinion this is the right behavior, even though the runtime may 
not recursively check dependents (depending on inheritance), defining 
circular dependencies in configs should be wrong.
if the others agree with this, it could be nice if the new algorithm 
checked for this, and still is faster than the current ;)
