in reply to About "state" variables in Perl 5.10

Since I find the latter very simple to follow and understand I would like to know if there are differences between them
Er... between what?

Do you know the difference between a hippo?

<Reveal this spoiler or all in this thread>

Each sub has its own scope, so sharing a lexical state variable via state $var is not an option, you have to allocate that var in an outer scope. my and state make no difference there.

--shmem 

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
