It is universally supported but not always in the same way, which is why
it hasn't managed to become part of POSIX.
I for example stumbled upon an issue where 'local x' does not work the
same in bash and zsh, triggering a huge discussion on the zsh mailing

However, if you set a value (e.g. 'local x=') then you shouldn't have
any problems.
f () { local x; echo ${x-unset}; }; f # this behavior varies
