I'm sorry if you think I mischaracterized your work, and I see in retrospect that my wording was overly judgmental. Here's the point I was trying to get at. The discussion threads about the Module have been superficially about the mechanism, but I think at the root of these discussions are the following two and a half questions:
1) What should be a Module (now that we understand what that implies in addition to a directory move)?
1)a) In addition to what specific existing code should be a Module, what standards should we apply in the future?
2) To what extent should Module-like techniques be applied to non-Modules?
I think if we all have a shared understanding of the answers to these questions, it will greatly reduce the confusion/controversy around Module-related changes, and therefore make it easier for you and the others working on this project to get your work done
Below is my understanding of the current state of the code and potential future plans, which anyone more knowledgable should feel free to correct.
Once we have the right list to look at, I'm sure I and others will have comments about specifics. For example, I think File API (as opposed to Filesystem API more specifically) would be a poor candidate for a module since it is used by core code. However, I'd like to make sure I'm looking at the right data before I comment, since I'm not sure modularizing File API is even part of the plan any more.
