It's not on the list but I'm hoping to convince Dino to work on END_FINALLY to be a bit more sane.

Following the converting 8-bit bytecode to 16-bit bytecode (wordcode),

there are other issues for improving the bytecode.

1. http://bugs.python.org/issue27129

Make the bytecode more 16-bit oriented.

2. http://bugs.python.org/issue27140

Add new opcode BUILD_CONST_KEY_MAP for building a dict with constant

keys. This optimize the common case and especially helpful for two

following issues (creating and calling functions).

3. http://bugs.python.org/issue27095

Simplify MAKE_FUNCTION/MAKE_CLOSURE. Instead packing three numbers in

oparg the new MAKE_FUNCTION takes built tuples and dicts from the stack.

MAKE_FUNCTION and MAKE_CLOSURE are merged in the single opcode.

4. http://bugs.python.org/issue27213

Rework CALL_FUNCTION* opcodes. Replace four existing opcodes with three

simpler and more efficient opcodes.

5. http://bugs.python.org/issue27127

Rework the for loop implementation.

6. http://bugs.python.org/issue17611

Move unwinding of stack for "pseudo exceptions" from interpreter to

compiler.
