Destructuring assignment

the example from the CS-hompage run with CS 1.10 / browser(chrome) / latest

futurists =  sculptor: "Umberto Boccioni"  painter:  "Vladimir Burliuk"  poet:    name:   "F.T. Marinetti"    address: [      "Via Roma 42R"      "Bellagio, Italy 22021"    ]{poet: {name, address: [street, city]}} = futuristsconsole.log futuristsconsole.log "'street' defined ?", street?, (street if street?)console.log "'poet' defined ?", poet?, (poet if poet?)console.log "broken CS ? why is 'poet' in 'ref' ?", eval('ref').name

I'm bringing this up, 'cos i can't figue out the current the status of 'destructuring assignments'.
I'm not sure if that is expected behaviour. I'd expect 'poet' to be avail in local-scope.
There has been some discussions during 2013 at CS-github.issues.page eg.Issue 3500,Issue 3225

I'd like to be able to assign to a local var :

b = {}b.{poet: {name, address: [street, city]}} = futurists

This has been proposed before - the regarding issue(s) is/are solved | closed. The status is unclear to me ?
So i vote for it in CS6.
