Take this example from std.path.absolutePath:

assert (absolutePath("../file", "/foo/bar")    == "/foo/bar/../file");

Note the ../ in the path. absolutePath does note return the canonical path (which is what I would have expected it to do), but even if it's better for absolutePath to not return the canonical path, we still need a function which will do that, and I don't see one in std.path which does.

So, I think that either absolutePath should be changed to return the canonical path (which presumably it has a good reason for not doing), or std.path needs a new function which does.

Okay, it looks like we already have buildNormalizedPath which does some of what needs to be done for canonicalizing a path (it gets rid of ., .., and / from a path), but it doesn't follow symlinks, so it doesn't actually get a canonical path (every file should have one and only one canonical path). So, this request isn't quite as critical as I was thinking that it was, but we do still need a function for returning the canonical path of a file or directory.
