That wasn't really asked by your original link. While not common, people do
ask in #zsh why after attempting to use an local (non-readonly)
variable named path to reference an filename or something, they can no longer
execute commands. Using typeset's -h option to hide the special attribute allows
them to do so, so setting it `42' like in the stackexchange link would work
without breaking other stuff.
But to actually allow what you are now asking, I'll defer to someone else.
