I'm trying to understand what last stack frame (or lack of a last
stack frame, or the faking of a lack of a last stack frame) you are
talking about. Your original message shows some tracebacks, but
doesn't have the code that produced them. It's hard to understand
what you are referring to.
Well, if you looked at that stack trace, you saw the code:
Traceback (most recent call last):
File "pseudoc_tool.py", line 91, in <module>
first_class_function_value(func, **pass_params)
TypeError: print() got an unexpected keyword argument 'noann'
So yes, the code is:
---
first_class_function_value(func, **pass_params)
---
That's the "calling code". And the rest of the code? But's that's the
whole point, that the current CPython's error reporting doesn't tell me
where it is! It just tells me the function name, and go make a
full-text search thru the entire sys.path to find its location,
especially if there're many functions of that name.
Perhaps instead of fiddling with stack frames, we can solve this problem
in a more straightforward way. The error message has a description of
the function: "print()". What if we extend that description: "print()
at path/to/myprog.py:173". Then the existing stack traces would have
the information you want, without having to debate the meaning of stack
frames, and where execution happens.
