I’ll keep that in mind. I’m very new to mailing lists, and I haven’t found any resource on properly using mailing lists, unfortunately. 
And yes, if we use an external program (or even just `command true`), the bug won’t appear. Though it does with function calls, too:
zsh -c 'v=1; ff() command true ; f() { local v; v=2 ff; }; f; typeset -p v'
