I’ve started (but not finished) a dozen spare time projects. I’ve had hundreds of new ideas, and a few of them were even interesting. I’ve learned a lot, but not enough (it’s never enough).

It treats directory elements like iterators, and has a convenience iterator that flattens the problem of iterating through a directory tree recursively. The only examples I found for it were in their extensive test sources, (See convenience tests and operations tests for more examples.) which are a bit light on comments. ...
