Coffeescript: Invoking call on function declaration

Computed properties on ember views have the form

myComputedProperty: function() {
    return doSomething();
}.property()

However, when I write this in coffescript as 

myComputedProperty: ->
    doSomething()
.property()

I get an error like "Parse error on line 5: Unexpected '.'". Am I doing something wrong, or is this a quirk of the interpreter I'm using (Mindscape VS plugin)?

You can add () around the function, or you can make the syntax more coffeescript friendly:

prop = (fn) -> fn.property()

myComputedProperty: prop ->
    doSomething()

The grammar of the language doesn't support this. You have to add parenthesis around the function:

myComputedProperty: (->
    doSomething()
).property()
