in thread 'my' and 'state' declaration inside a loop

state is not an 'improvement' of my. It is an improvement of Perl to provide a small feature that was missing - scoped static variables. The common part between my and state variables is that they can't be accessed by name outside their lexical scope. The prime difference between them is that my variables get a fresh chunk of memory each time their lexical scope is entered whereas static variables are assigned a chunk of memory at program start time and retain it until execution terminates.

True laziness is hard work
