Blocks

Blocks are a simple extension to C (as well as Objective-C and C++) that make it easy

for you to define self-contained units of work. A block in code is denoted by a caret at

the beginning of a function. For example, you could declare a block and assign it to x

by writing:

x = ^{ printf("hello world\n"); }

This turns the variable x into a way of calling the function so

that calling x( ); in the code would print the words hello world.
