Re: a note on notations

I'm flogging a dead horse, but I'd like to point out the invoking a
function also involves a lookup into the environment, but I don't seem
to need to use $.  (And invoking a program involves a lookup into the
namespace defined by $path, but again, I see no $.)  Also, by use of $
in primitives, there is an implication that they can be over-ridden by
assignment -- this does not appear to be the case.  Finally, when I try
"echo $&home", nothing happens.

As the only person on this list who seems to have used rw indirection,
why did you need it, John?
