The example in Loops and Comprehension generates invalid javascript:

names = sam: seaborn, donna: moss
alert("#{first} #{last}") for first, last of names

generates

var first, last, names;

names = {
sam: seaborn,
donna: moss
};

for (first in names) {
last = names[first];
alert("" + first + " " + last);
}


This javascript cannot be run: reference error on variable seaborn.

Stich It Up

I tried the code sample in this section using the latest versions of node(0.8.16), and express(3.0.5).

I recorded the changes that need to be made for that code to be compatible with those versions here: https://gist.github.com/4393079/revisions

Apologies if this was the incorrect destination for such feedback.
