should probably go through a testing phase (checking its result against that of eval_domain_and_context) for a while, but apart from that it's supposed to work. 'stdlib' stuff (datetime.date.today, datetime.timedelta, time.localtime, time.time, time.strftime) still need to be written. Isn't there also a dateutil.relativedeleta somewhere? Anyway that needs to be done and the various evaluation contexts need to be defined, but the valuator itself should mostly work. bzr revid: xmo@openerp.com-20120227073721-nkgeiqacbzch8xev

Evaluator
|
|
---------
|
|
|
|
* Builtins should be built-in, there should be no need to add e.g. ``py.bool`` to the evaluation context (?)
|
|
* Stop busyworking trivial binary operator
|
|
* Make it *trivial* to build Python type-wrappers
|
|
* Implement Python's `data model protocols
|
|
<http://docs.python.org/reference/datamodel.html#basic-customization>`_
|
|
for *all* supported operations, optimizations can come later
|
|
* Automatically type-wrap everything (for now anyway)
|
|
|
|
