• 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

Jaspy

• 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
