Cannot get ES6 functions in Node 0.11.13 running --harmony flag

Question

I ran

nvm install 0.11.13
node -v returns 0.11.13

Yet when I try to run something like:

var test = [1,2,3,4,5,6,7];
test.map(item => item);

node --harmony test.js

I get

/root/test.js:3
test.map(item => item);
               ^
SyntaxError: Unexpected token >

Not sure what I'm doing wrong here.

Also:

node -e 'console.log(process.versions.v8);'
returns 3.26.33
