Regression 1.15.7 - 1.16.0, exports 'variable assigned to but never read'

[bazineta]

1.15.7 doesn't regard the following as a problem:

class Foo
...
module.exports = Foo

While 1.16.0 issues:

Class "Foo" is assigned to but never read

...which is, in fact, being issued by coffeescope2, not coffeelint.
