Thanks for the additions and corrections.

I was thinking of the standard forms -- but,
since I forgot {zo'u} I coudn't do them very well
either.  The {PA brivla} format will break down
early on for the restricted forms, though we can
do without them.

I think the {zo'u} format is safest; anything
less leaves -- as you say -- some arrangements
unsayable.  This gets even more pressing when we
get to the point of adding modals.

Strictly true, though I haven't seens a case
where the extra rounds were needed -- if you take
a liberal enough view of what counts as a
variable for these purposes.

My favorite argument for Polish notation.  Do we
really need TUhE-TUhO?  Aren't there a set of
reverse grouping and hierarchical grouping
markers that pretty much cover all cases (there
used to be)?  Parentheses are less messy however.
 And, in any case, something more than I noted is
needed.
