+Naming and binding
+-------------------------------------------------------------------
-If a name binding operation occurs anywhere within a code block, all
-uses of the name within the block are treated as references to the 
-current block. This can lead to errors when a name is used within a 
-block before it is bound. This rule is subtle. Python lacks declarations
-and allows name binding operations to occur anywhere within a code block.
-The local variables of a code block can be determined by scanning the
-entire text of the block for name binding operations.
