Subject: Re: [boost] boost::filesystem::path frustration

In a previous job, I had to work very heavily with file systems and Windows
registry trees.

For that use-case, I took paths and put them in a structure that
represented a tree view of the system. That is, I iterated over the file
system and created a tree to represent all the paths.

Currently, I use the file system in a very light sort of way, and I very
much enjoy the use of boost::filesystem as it exists. As such, I'm not sure
I'd want to change it overmuch from its current behavior. If anything, I
almost wish we had a boost::registry for Windows that provided much of the
same kind of functionality in boost::filesystem, but for the Windows
registry. I say 'almost', though, because I don't really like to use the
Windows registry at all, and use INI files for configuration information

If I had to return to my previous job, though, I would probably want to use
a directory iterator to help build a tree, and to extract
boost::filesystem::path objects out of that tree as desired. But then, I'd
also want somewhat complicated algorithms that compared different trees to
obtain differences (paths removed or created).

Would it be helpful to have a kind of boost::tree that could be built by
one or more iterators, which had properties like a container, but
generali(z/s)ed such that it could be built by iterators over a file system
or a Windows registry, or some other mechanism that can build trees?
