Nobody called me out on that ... the first assignment is actually just
fine.  I'm not sure how I ended up thinking that didn't work.  There
is, however, a related buglet:

% setopt extendedglob
% typeset -U CDPATH
% typeset -mp '(#i)cdpath'
typeset -aT CDPATH cdpath=(  )
typeset -UT CDPATH cdpath=(  )

Note the -U attribute is only retained when printing the assignment
for the scalar ... which is literally correct, since it was only
asserted for the scalar, but lossy, whereas the array-ness is
preserved in both cases (as long as typeset remains a reserved word).
