This brings up a discussion which should *not* be carried on further
in this group: everybody's favorite unimplemented operators.

Just to break my own rule, I propose
	spp->>f == (*spp)->f  == (**spp).f
for dereferencing "handles".  Perhaps a better solution would be to define
a right-binding dereference operator, "^", so that we could say
	s.f ==  sp^.f == spp^^.f
and not need any funny precedence-hacks.  Isn't originality wonderful? :-)

BTW, I'm curious why the "." and "->" operators aren't real operators.
Obviously there isn't any standard type for their right operand, but
is the answer more subtle than this?
