Coding Style Tips

• By default, the new C11 functions follows this name: pkpy_{class}__{function}
• Use T* self as the first parameter if the function is a previous C++ method
• Do not change PyVar and PyObject
• Do not change Enums
• Use comment T= to annotate generic array and vector, e.g. c11_vector/* T=c11_string */
• Use a single line // comment for function if it is not clear

TODO:

1. rename ::PyVar to pkpy_Value
2. rename ::PyObject

It looks like you have dropped support for multiple VMs in v2 and instead use pk_current_vm. Is that a feature that will come back?

Paritially. v2 still supports multi-vm. You can keep multi-vm states but only one of them can be active. And all operations are based on the current active vm. We will introduce a API like py_switch_vm which allows you to switch between VMs.
