In some cases the type of a method's result may depend on the type of its arguments. 
To accurately express the signatures of such methods one may use parametric polymorphism. 
A parametrically polymorphic method signature introduces one or more formal type arguments
which can be used throughout the signature and the method body. When the message is sent,
the actual types will be inferred and replace the formal type arguments in the signature. 
As an example, consider the signature of -[NSArray[T] mapArrayUsingBlock:]

- (NSArray[X]) mapArrayUsingBlock: (X (^)(T obj) block;

The type term X def introduces a type argument X, which will be inferred to be the type returned
