Hello,
I'd like to open up the idea of Path being an object in std.path. I've submitted a pull (https://github.com/D-Programming-Language/phobos/pull/1333) that adds a Path struct to std.path, "which exposes a much more palatable interface to path string manipulation".

Let me add some more to this. To justify the addition of such a type, it needs to pull its own weight. For added value, it could do one or both of the following:

Does System.IO.DirectoryInfo:

Add sufficient value to justify it's existence to your mind?

vs just having System.IO.Directory:
http://msdn.microsoft.com/en-us/library/system.io.directory.aspx

They add great value, but that is a completely different discussion, as these are more similar to std.file.DirEntry. The added value is mainly in the performance benefits; for example,

    if (exists(f) && isFile(f) && timeLastModified(f) < d) ...

requires three filesystem lookups (stat() calls), whereas

    auto de = dirEntry(f);
    if (de.exists && de.isFile && de.timeLastModified < d) ...

is just one.

I see no such benefit in the proposed Path type.
