Some built-in functions and theinpsectmodule require built-in types like cell, traceback, or frame objects, and they can't use the corresponding interpreter classes. Here is an example of this inByterun: class__init__functions don't get traced into, because the built-in function__build_cl...
Python also supports functions-as-first-class-citizens out of the box, in terms of passing a function as a parameter, such as what you might use in the map global function, which executes a function over each element of a list:
