I think any kind of attempt at a generic filing syntax for all
systems could be complicated. RISC OS uses '.' for
directory separator and '$' for the root directory, but a
canonicalized pathname must also contain a prefix specifying
the filing system and medium title. So Mem::Memphis.$.Scrap.Mytext
(Mem is a RAMDisc filing system) will be different from
ADFS::Iyonix.$.Scrap.Mytext (ADFS is a hard disc filing system),
though both could be described as /Scrap/Mytext from
the Unix filenaming point of view. In theory users can write
their own filing systems, using their own syntactic preferences.
Finding even an abstract syntax to cover all eventualities
sounds dodgy to me.
