Some issues to discuss

[mwager]

Hey, I really like your project and it looks good to our team. There are some issues though I want to discuss here:

1) Loop variables are never read

for key, val of someObject
  doSomethingWith(val)

gives me:

✗ #1: Variable "key" is never read ( first defined on line 1).

Is there an option to ignore this? I know I could write this in another way but it's nice to use the for ... of syntax here.

2) Undefined identifier if used before defined

foo()

foo = ->
  return 1

gives:

✗ #1: Undefined identifier "foo".
✗ #3: Variable "foo" is never read ( first defined on line 3).

This cannot be correct because foo is defined within the scope.

3) Variable never read

describe 'some spec', ->

  foo = null

  beforeEach ->
    foo = 1

gives:

✗ #3: Variable "foo" is never read ( first defined on line 3).
✗ #6: Variable "foo" is never read ( first defined on line 3).

Same:

intervalId = setInterval ->
  clearInterval intervalId
, 50

-> Variable "intervalId" is never read

Thanks for the reports!

To ease communication and tracking, I'm going to split all mentioned issues in separate requests!
