in reply to Autoboxing by subclassing CORE

What version of Perl is needed to make it run? I am getting

Can't locate object method "substr" via package "String" at - line 20.
in 5.14.2.

    I'm using 5.16. perl5160delta notes various improvements to the CORE and CORE::GLOBAL namespaces. Perhaps in earlier Perls CORE::substr doesn't work, but some other interesting CORE functions are likely to work.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
