Detailed Description

Native Frame

A struct that holds the execution frame of a native function, including the args and single stack slot, and pointer to the code object.

This struct doesn't need an OD because it is only used statically in the globals struct. There's only one native frame, the global one. This happens because a native function is a leaf node in the call tree (a native func can't call python funcs).
