The rule isn't entirely obvious. If a decomposition function can possibly
return more that one element, it is returned as type path. If at most a
single element is returned, the return type is std::string.
Yes, via the automatic conversion. I just added a test case to path_test to
verify that. Yes, it does work. I expect there would have been scads of bug
reports if it didn't work.
