JSONDecodeError verbose error mesage

Feature or enhancement

Proposal:

Example is the best way to start:

import json

try:
    raw_json_dict = b"{'a': 1, {'b': 2 'c': 3}}"
    letter_to_index = json.loads(raw_json_dict)
except JSONDecodeError as error:
   print(error.verbose())

# Printing => verbose error:"'b': 2 'c': 3}"

The problem:
Currently, when getting a JSONDecodeError you can't fully understand where the issue is because of unindecative error message.
The message only gives you the location of the error but not what actually caused the error itself.
For example, when you try to json.loads() a response from a server and you don't know what the content will be.
If you got a JSONDecodeError and you didn't log or save the raw response fron the server, you won't be able to figure out what caused the error and fix it.

The solution
First, I am not here to propose one unique solution, there could be multiple possible solutions. I just want to present the simple one to show its impact.

The solution I proposed in the example makes use of new function inside the JSONDecodeError class.
The verbose function prints the actual characters in which the error occurred and print a range of chars around them to get a context of the error.
Furthermore, the function will be able to get a parameter which will defines the range of characters around the error to get back.

I would very like to hear your opinions of this feature.
Thanks!

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
