2. Don't declare auto variables in nested function blocks.
Variable declarations in nested blocks are usually a good thing. But with
cc65, there are several drawbacks:
a. The compiler has only one symbol table (there's no true nesting).
This means that your variables must not have the same names as
variables in the enclosing block.
b. Since the compiler generates code in one pass, it must create the
the variables on the stack each time the block is entered and destroy
them when the block is left. This causes a speed penalty and larger
code.
