It's unusual, but I've done it once or twice. It looks like:
id obj;
if (.....)
obj = [Class1 alloc];
else
obj = [Class2 alloc];
obj = [obj initWithFoo:.... bar:....];
It's important that you reassign 'obj' to the value of the init call, since
initializers are allowed to return a different object than the receiver, and
the class-cluster design pattern takes advantage of this.
