More fodder:

(I didn't check that this is 100% compatible with the current API.)

this/is/stuff/last.my.name = path
this/is/stuff              = path.dirname()
               last.my.name = path.basename()
               last.my      = path.basename(".name")
                      .name = path.suffix()

this/is/stuff/ = path
this/is        = path.dirname()
         stuff/ = path.basename()
              / = path.suffix()

From Perl's File::Basename,
   It is guaranteed that

   # Where $path_separator is / for Unix, \ for Windows, etc...
   dirname($path) . $path_separator . basename($path);

   is equivalent to the original path for all systems but VMS.
