Support member functions

[amk221]

With the following...

foo: computed(function() {

}).volatile(),

bar: computed(function() {

})

I get the 'bar' multi-line function should be above 'foo' method, but I wasn't expecting to.

Ok, I didn't think about that case before. I agree this should be treated equally and not throw any error. Thanks for posting this issue @amk221 :)
