I thought about that option, if it was unclear to the parser that 
Point!int was the type to instantiate upon. Changing to the other 
syntax made me wonder what would happen when getResponse is 
calling itself, which in self was something I am a bit unsure of 
how to understand. Because we get the same syntax issue there and 
it does not seem to work.
