CoffeeScript: Accessing outer class objects from inner class instance - coffeescript

Question

If there any way to access outer class fields from inner class instance, EXCEPT passing outer class instance to inner class constructor?
To be more specific, I have a simple example:
class Test
constructor: (#number) ->
class SubTest
constructor: (#name) ->
toString: () ->
console.log #name, #number
getSubTest: () ->
return new SubTest "SubTest"
test = new Test 10
test.getSubTest().toString() # SubTest undefined
So, I want to get "SubTest 10" instead of "SubTest undefined". Is it possible?

Good news! It turns out if you create the closure over # yourself, it works just fine:
class Test
self = []
constructor: (#number) ->
self = #
class SubTest
constructor: (#name) ->
toString: () ->
#name + self.number
getSubTest: () ->
return new SubTest "SubTest"
test = new Test 10
v = test.getSubTest().toString()
alert v
Translates to :
var Test, test, v;
Test = (function() {
var SubTest, self;
self = [];
function Test(number) {
this.number = number;
self = this;
}
SubTest = (function() {
function SubTest(name) {
this.name = name;
}
SubTest.prototype.toString = function() {
return this.name + self.number;
};
return SubTest;
})();
Test.prototype.getSubTest = function() {
return new SubTest("SubTest");
};
return Test;
})();
test = new Test(10);
v = test.getSubTest().toString();
alert(v);
Output:
SubTest10

It's an old question but the accepted answer doesn't work if multiple instances of the outer class are needed (as pointed out by #costa-shapiro). Here is an alternative approach to create the closure with the inner class.
SubTest = (test) ->
class SubTest
constructor: (#name) ->
toString: () =>
console.log #name, test.number
class Test
constructor: (#number) ->
#SubTest = SubTest #
getSubTest: () =>
return new #SubTest "SubTest"
test = new Test 10
test.getSubTest().toString()
