2014-02-21	__import__: Catch relative import attempts and throw NotImplementedError.	Paul Sokolovsky

2014-02-20	import: Implement "from pkg.mod import sym" syntax properly.	Paul Sokolovsky
	http://docs.python.org/3.3/library/functions.html#__import__ : "When the name variable is of the form package.module, normally, the top-level package (the name up till the first dot) is returned, not the module named by name. However, when a non-empty fromlist argument is given, the module named by name is returned."
2014-02-16	builtinimport: Get the basic (and only basic) package imports work.	Paul Sokolovsky

2014-02-16	builtinimport.c: Recognize "namespace package" and error out as unsupported.	Paul Sokolovsky
	See http://www.python.org/dev/peps/pep-0420/#specification for spec. See https://github.com/micropython/micropython/issues/298 for the discussion of the implemented behavior.
2014-02-15	Implement proper exception type hierarchy.	Damien George
	Each built-in exception is now a type, with base type BaseException. C exceptions are created by passing a pointer to the exception type to make an instance of. When raising an exception from the VM, an instance is created automatically if an exception type is raised (as opposed to an exception instance). Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper. Handling of parse error changed to match new exceptions. mp_const_type renamed to mp_type_type for consistency.
2014-02-08	Make mp_obj_str_get_data return char* instead of byte*.	Damien George
	Can't decide which is better for string type, char or byte pointer. Changing to char removes a few casts. Really need to do proper unicode.
2014-02-06	Implement fixed buffer vstrs; use them for import path.	Damien George

2014-02-05	Search paths properly on import and execute __init__.py if it exists.	Damien George

2014-02-05	Implement support for sys.path when loading modules.	Paul Sokolovsky
	sys.path is not initialized by rt_init(), that's left for platform-specific startup code. (For example, bare metal port may have some hardcoded defaults, and let user change sys.path directly; while port for OS with environment feature can take path from environment). If it's not explicitly initialized, modules will be imported only from a current directory.
2014-02-04	Expose __import__() function.	Paul Sokolovsky

2014-01-25	Implement mp_parse_node_free; print properly repr(string).	Damien George

2014-01-22	Second stage of qstr revamp: uPy str object can be qstr or not.	Damien George

2014-01-21	Revamp qstrs: they now include length and hash.	Damien George
	Can now have null bytes in strings. Can define ROM qstrs per port using qstrdefsport.h
2014-01-20	Implement modules as singletons Python semantics.	Paul Sokolovsky
	In Python, importing module several times returns same underlying module object. This also fixes import statement handling for builtin modules. There're still issues: 1. CPython exposes set of loaded modules as sys.modules, we may want to do that either. 2. Builtin modules are implicitly imported, which is not really correct. We should separate registering a (builtin) module and importing a module. CPython keeps builtin module names in sys.builtin_module_names .
2014-01-18	Add source file name and line number to error messages.	Damien George
	Byte code has a map from byte-code offset to source-code line number, used to give better error messages.
2014-01-15	Convert parse errors to exceptions.	Damien George
	Parser no longer prints an error, but instead returns an exception ID and message.
2014-01-13	Cleanup built-ins, and fix some compiler warnings/errors.	Damien George

2014-01-04	Split qstr into pools, and put initial pool in ROM.	Damien George
	Qstr's are now split into a linked-list of qstr pools. This has 2 benefits: the first pool can be in ROM (huge benefit, since we no longer use RAM for the core qstrs), and subsequent pools use m_new for the next pool instead of m_renew (thus avoiding a huge single table for all the qstrs). Still would be better to use a hash table, but this scheme takes us part of the way (eventually convert the pools to hash tables). Also fixed bug with import. Also improved the way the module code is referenced (not magic number 1 anymore).
2014-01-03	Change mp_compile so that it returns a function object for the module.	Damien George

2014-01-03	Basic implementation of import.	Damien George
	import works for simple cases. Still work to do on finding the right script, and setting globals/locals correctly when running an imported function.
