* Builtins are exposted to frame.f_builtins
|
|
* f_builtins is assigned during frame creation,
|
|
self.f_builtins = f_locals['__builtins__']
|
|
if hasattr(self.f_builtins, '__dict__'):
|
|
self.f_builtins = self.f_builtins.__dict__
|
|
* f_locals has a __`____builtins___` field which is directly the `__builtins__` module

|
* The `module()` function creates either a NativeModule or PythonModule
|
|
* The objects in the module are PyType.native
|
|
* The function call is abstracted as a `call` function, which handles different
|
|
|
|
* IMPORT_NAME depends on `__import__()` in builtins

TODO:
|
|
|
|
* Implement a new type NativeFunction
|
|
* Wrap a function pointer in NativeFunction
|
|
* Refactor the CALL_FUNCTION case so it can call both python function and native function
|
|
* During frame creation, force push a nativefunction `print` into the namespace
|
|
* Modify LOAD_* so they can search for names in builtins
|
|
|
|
* Create a module type
|
|
* In VM initialization, load the builtins module into locals
|
|
* During frame creation, create a field that conatins the builtins dict
