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.
