coffeescript + jshint = Unused variable: _this

Compiling any code with bare = false and linting it with JShint
results in Unused variable: _this.

Solutions to this?
bare = true should remain,
besides I'm pretty happy to have jshint checking for unused variables. I just want an exception here.

By the way, I also get the

Move the invocation into the parens that contain the function.
}).call(this);

If you really want to run the generated JS through JSHint, you can pass options to ignore this warnings like so:

###jshint node: true, unused: false ###

which compiles to

/*jshint node: true, unused: false */

Why are you running stuff you have written in Coffeescript through jshint? Isn't jshint supposed to be used with handwritten javascript?

If you really want to use a lint tool why don't you use http://www.coffeelint.org/

Lastly this is very similar to the question here, which was closed as not being a real question.
