Thanks everybody who replied.
From the conversation, I now understand why the two line version
didn't have the compiler warning while the one line version did: once
the +alloc was assigned to an ivar, the compiler then knew which of
the multiple -init methods to use. I thought I was adding value with
my approach, but I know see the troubles I was causing... Enough said.

Well because you simply cannot do this. Somehow every single class
would have to declare their own version of the +alloc method that
returns an object of their specific type. Do you really want the
hassle of having to do that every single time you create a
subclass? This is not something that can be changed in the
framework, but would have to be a change to the language/runtime.
