for boost::filesystem::path I would suggest an operator + that works like the following fs::path("foo") + "bar" -> "foobar" fs::path("foo") + "/bar" -> "foo/bar" fs::path("foo") / "bar" -> "foo/bar"
What's the situation in which you'd like to use that operator?
Sometimes I have file formats that have two parts, e.g. a description xml file and a data file. then I'd like to do name + ".xml" and name + ".dat" if name is a fs::path
Note that Boost.Filesystem contains functions to retrieve and modify file extensions. In my opinion, introducing such a free + operator would be quite bad, as it would encourage use of it to glue on path segments in ways that may violate the format of paths for a platform, as in your example of an unconditional +"/bar", which would be horribly wrong for any platform that didn't use / as separator. -- Lars Viklund | zao@acc.umu.se
