7c4316d4fb Start handling pypy 2.7 
Need to understand whether we care compiling pypy.
Pypy 2.7 list comprehensions are different and use
its own opcode.

063e517a7c Better parse error formatting 
Start to move away for compiler-oriented terminology:
   Favor "instructions" over "tokens".
Syntax error -> Parse error.

0ee52aeeef Isolate pseudo op IMPORT_NAME_CONT 
I think this is a holdover from pre 2.3 days. Possibly it can be dropped altogether.

fa7d8f955a WIP Python-2.6 but don't remove opcodes 
The scheme for turning 2.6 bytecode into 2.7 psuedo bytecode
I think is a lose.

I won't work for fragment handling.

Instead, change the grammar and syntax rules

This also has the benefits:

* We see how code generation changed over releases
  by looking at grammar and semantic rules rather
  than arbitrary code
* We can better assocate with what's running
  (in a sense this is a restatement of broken fragment
   handling)
* With the right structure in place we are in a better position to
  handle 2.5, 2.4, etc. That is, after a while, the incremental changes
  to get say from python 2.3 bytecode to python 2.7 are great.

problem was handling in Python 3.2
