I agree, so am fixing this.

symbol table for each top-level compilation unit.  The information in
the symbol table allows the elimination of the later optimize() pass;
the bytecode generation emits the correct opcodes.

The current version passes the complete regression test, but may still
contain some bugs.  It's a fairly substantial revision.  The current
code adds an assert() and a test that may lead to a Py_FatalError().
I expect to remove these before 2.1 beta 1.

The symbol table (struct symtable) is described in comments in the
code.

The changes affects the several com_XXX() functions that were used to
emit LOAD_NAME and its ilk.  The primary interface for this bytecode
is now com_addop_varname() which takes a kind and a name, where kind
is one of VAR_LOAD, VAR_STORE, or VAR_DELETE.

There are many other smaller changes:

- The name mangling code is no longer contained in ifdefs.  There are
  two functions that expose the mangling logical: com_mangle() and
  symtable_mangle().

- The com_error() function can accept NULL for its first argument;
  this is useful with is_constant_false() is called during symbol
  table generation.

- The loop index names used by list comprehensions have been changed
  from __1__ to [1], so that they can not be accessed by Python code.

- in com_funcdef(), com_argdefs() is now called before the body of the
  function is compiled.  This provides consistency with com_lambdef()
  and symtable_funcdef().

- Helpers do_pad(), dump(), and DUMP() are added to aid in debugging
  the compiler.

Also fixes two long-standing bugs (present in 2.0):
1. .join() didn't check that the result size fit in an int.
2. string.join(s) when len(s)==1 returned s[0] regardless of s[0]'s
   type; e.g., "".join([3]) returned 3 (overly optimistic optimization).
I resisted a keen temptation to make .join() apply str() automagically.

  The BaseServer class was created, for example, to poll a table in a MYSQL

  Handler which deals with the entry.

  With this patch, using BaseServer and ThreadedServer classes, the creation
  of the server that reads and handles MySQL table entries instead of a
  socket was utterly trivial: about 50 lines of python code.

  You may consider this code to be utterly useless [why would anyone else
  want to do anything like this???] - you are entitled to your opinion. if you
  think so, then think of this: have you considered how to cleanly add SSL to
  the TCPSocketServer? What about using shared memory as the
  communications mechanism for a server, instead of sockets? What about
  communication using files?

  The SocketServer code is extremely good every useful. it's just that as it
  stands, it is tied to sockets, which is not as useful.

I heartily approve of this idea.

I found where rich comparison of unequal recursive objects gave
unintuituve results.  In a discussion with Tim, where we discovered
that our intuition on when a<=b should be true was failing, we decided
to outlaw ordering comparisons on recursive objects.  (Once we have
fixed our intuition and designed a matching algorithm that's practical
and reasonable to implement, we can allow such orderings again.)

- Refactored the recursive-object comparison framework; more is now
  done in the support routines so less needs to be done in the calling
  routines (even at the expense of slowing it down a bit -- this
  should normally never be invoked, it's mostly just there to avoid
  blowing up the interpreter).

- Changed the framework so that the comparison operator used is also
  stored.  (The dictionary now stores triples (v, w, op) instead of
  pairs (v, w).)

- Changed the nesting limit to a more reasonable small 20; this only
  slows down comparisons of very deeply nested objects (unlikely to
  occur in practice), while speeding up comparisons of recursive
  objects (previously, this would first waste time and space on 500
  nested comparisons before it would start detecting recursion).

- Changed rich comparisons for recursive objects to raise a ValueError
  exception when recursion is detected for ordering oprators (<, <=,
  >, >=).

Unrelated change:

- Moved PyObject_Unicode() to just under PyObject_Str(), where it
  belongs.  MAL's patch must've inserted in a random spot between two
  functions in the file -- between two helpers for rich comparison...
