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:
|
||
|
|
***********************
|
||
|
|
|
||
|
|
* int
|
||
|
|
* float
|
||
|
|
* --str-- unicode
|
||
|
|
* bool
|
||
|
|
* dict
|
||
|
|
* tuple
|
||
|
|
* list
|
||
|
|
* ?module
|
||
|
|
* ?object
|
||
|
|
* datetime.time
|
||
|
|
* datetime.timedelta
|
||
|
|
* NotImplementedType
|
||
|
|
|
||
|
|
Base methods requirement
|
||
|
|
************************
|
||
|
|
|
||
|
|
* ``__getattr__``
|
||
|
|
* ``dict.get``
|
||
|
|
|
||
|
|
In datamodel, not implemented in any type, untested
|
||
|
|
***************************************************
|
||
|
|
|
||
|
|
* a[b]
|
||
|
|
|
||
|
|
* a + b, a - b, a * b, ...
|
||
|
|
|
||
|
|
* +a, ~a
