Class won't compile if code is wrapped in curly braces

When I'm writing a custom component, I simply cannot use curly braces/brackets to evaluate an expression.

The following code won't compile/transform:

``` cjsx
App = React.createClass
  render: ->
    {@props.children}
```

CoffeeLint and CJSX itself throw the following error:

```
[stdin]:6:12: error: unexpected . at line 6 col 5
```
