Perhaps it does that, but also emits a warning e.g. 'implicit initial value for future-scoped lexical' or something like that. > for 1,2 -> $x { > END { say $x } > } undef, because END is like a declaration putting the closure in some global, and doesn't actually happen at runtime. Otoh for 1,2 -> $x { state $y = $x; END { say $y } } Might work -- Yuval Kogman <[EMAIL PROTECTED]> http://nothingmuch.woobling.org 0xEBD27418
