FileSystemEnumerable ordering

[richard-fine]

Does System.IO.Enumeration.FileSystemEnumerable<TResult> make any guarantees about ordering of items?

I imagine the order might not be fully specified in order to permit e.g. parallelization, BFS vs DFS on different filesystems, etc - but even limited claims could be helpful. For example, are directories guaranteed to be enumerated prior to children of those directories?

The current implementation uses BFS to search directory. However, the API owners may not want to make a strong guarantee in the future.

Right, I get that guaranteeing BFS may be a bad idea. Wondering if they could guarantee some properties though.
