While trying to understand what Sebastian meant I've accidentally
discovered an unorthodox way to unset a parameter.

    unset2() {
      local _"$1"
      typeset -gT _"$1" "$1"
    }

Test:

    % foo=hello
    % unset2 foo
    % typeset -p foo
    typeset: no such variable: foo

I sort of understand why that happens but it doesn't look intended.
