If you mean an array value to which you can (in the same operation)
apply expansion flags such as joining, not really, no.
If you mean without having to declare a temporary name, you can use
the positional parameters:
set -- $p 'string' whatever else
print -r -- "${(j.#.)@}"
Of course that means knowing $@, $1, $2, etc. aren't being used for
anything else.
