[issue21911] "IndexError: tuple index out of range" should include the requested index and tuple length

[Ram Rachum]

Ram Rachum added the comment:

Josh, I agree with most of what you're saying. (Except the tips about debugging are not helpful, the point is to get the information as quickly as possible without having to make code modifications if possible.)

I can totally understand a reaction of "Your idea is helpful because it makes it easier to debug problems in your code quickly, which is a very important thing, but we prefer not to implement it because it'll introduce a considerable performance penalty." (Or use the -100 points argument which is depressing but valid.) 

But when people (like Raymond and Mark here) are not even acknowledging the obvious advantages of the suggestion before shooting it down, that is really frustrating, and next time someone on python-dev writes a blog post "why don't more people contribute to CPython", they should be looking at behavior like this.
