it is possible, but not in the sense you mean. for example an
implementation for urls can be provided. and you can write
  copy ("http://www.boost.org/index.htm", "file:/home/jan/index.htm");
currently it is assumed that the contents of both strings must be valid
descriptors to filenames on the specific platform. and if they are the
result of copy is the obvious one (copy the file). but the format of the
strings is implementation defined.

probably we should consider changing remove_leaf() to parent() with this
new meaning.
