You see, with the Path class the above function could be written as

def normalizePath(p, *pathParts):
    """ Normalize a file path, by expanding the user name and getting
    the absolute path..
    @param p [Path] = a path to a file or directory
    @param pathParts [list of string/Path] = optional path parts
    @return [Path] = the same path, normalized
    """
    tp = p.expanduser().abspath()
    return tp.joinwith(*pathParts).abspath()

That's clearly an improvement, isn't it?
