Array of anonymous objects with coffeescript

Question

How do I create an array of anonymous objects with the least number of characters with coffeescript?

Here's how little I've got it down to (works):

cast:
    [ {name: 'Rob Jr.', character: 'Tony Stark'}
      {name: 'Sam Jackson', character: 'Nick Fury'}
      {name: 'Daniel Craig', character: 'James Bond'} ]

I was hoping to be able to do this:

cast:
    [ name: 'Rob Jr.', character: 'Tony Stark'
      name: 'Sam Jackson', character: 'Nick Fury'
      name: 'Daniel Craig', character: 'James Bond' ]

However I get the error:

SyntaxError: [stdin]:20:9: unexpected :

It gets confused by the first colon it encounters. Is there some coffeescript magic I'm missing?

You can format it like this:

cast: [
  name: 'Rob Jr.', character: 'Tony Stark'
, 
  name: 'Sam Jackson', character: 'Nick Fury'
, 
  name: 'Daniel Craig', character: 'James Bond' 
]

Whenever I have a long large list I like to use a csv-style array. I think it also adds to readability. Like this:

rows = [
  ["a", "b", "c"]
  [  1,   2,   3]
  [  4,   5,   6]
]

objects = []

columns = rows.shift()

for r in rows
  o = {}
  for c, i in columns
    o[c] = r[i]
  objects.push(o)

alert(JSON.stringify(objects, null, 2))

I have a the code to convert it into the array of objects form in a function in my reusable library. I bet there is something similar in underscore.
