Note in passing that if the TYPESET_TO_UNSET option is in effect, the
first of those three is not equivalent to the other two.

Similarly.

This exposes another case where only "typeset" can provide full information.

% typeset +m foo
integer foo
% printf "<%s>\n" $parameters[foo]
<>
%

The parameter is unset and so not in $parameters, but typeset
"remembers" that it is an integer.
