title: What is the syntax for creating a local (stack allocated) reference to a block in Objective-C?
body: <p>I'd like to create a local reference to a block to be handled differently depending on the execution context.  Normally I would define a special block type and assign the block to that type, but this is more of one-off situation and doesn't really merit a special type declaration.  What is the syntax for creating a local reference to a block without using a custom type definition?</p>
