2014-04-09py: Properly implement deletion of locals and derefs, and detect errors.Damien George
Needed to reinstate 2 delete opcodes, to specifically check that a local is not deleted twice.
2014-04-08py: Remove DELETE_SUBSCR opcode, combine with STORE_SUBSCR.Damien George
This makes the runtime and object APIs more consistent. mp_store_subscr functionality now moved into objects (ie list and dict store_item).
2014-04-08py: Finish implementation of all del opcodes.Damien George
At this point, all opcodes are now implemented! Some del opcodes have been combined with store opcodes, with the value to store being MP_OBJ_NULL.
2014-03-31py: Add LOAD_NULL bytecode and use it to simplify function calls.Damien George
Adding this bytecode allows to remove 4 others related to function/method calls with * and ** support. Will also help with bytecodes that make functions/closures with default positional and keyword args.
2014-03-26py: Support closures with default args.Paul Sokolovsky
2014-02-01py: Tidy up BINARY_OPs; negation done by special NOT bytecode.Damien George
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new special NOT bytecode.
2014-02-01py: Implement break/continue from an exception with finally.Damien George
Still todo: break/continue from within the finally block itself.
2014-02-01Implement default function arguments (for Python functions).Paul Sokolovsky
TODO: Decide if we really need separate bytecode for creating functions with default arguments - we would need same for closures, then there're keywords arguments too. Having all combinations is a small exponential explosion, likely we need just 2 cases - simplest (no defaults, no kw), and full - defaults & kw.

2013-12-21Change object representation from 1 big union to individual structs.Damien
A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
