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)
|
|
|
|
Base type requirements:
