type

Something I've been wondering about recently is how to organize types in directories/namespaces w.r.t. their dependencies.

One method I've seen, which I believe is the recommendation for both Haskell and .NET (though I can't find the references for this at the moment), is:

Type
Type/ATypeThatUsesType
Type/AnotherTypeThatUsesType

My natural inclination, however, is to do the opposite:

Type
Type/ATypeUponWhichTypeDepends
Type/AnotherTypeUponWhichTypeDepends

Questions:

Is my inclination bass-ackwards?
Are there any major benefits/pitfalls of one over the other?
Is it just something that depends on the application, e.g. whether you're building a library vs doing normal coding?
