Hi,
I'm working on code where the function take a (x, y) set of coordinates.
If the coordinates are out of range/bounds, I want to raise an exception
with a message explaining the reason and limits. I definitely don't want
to "silently do nothing".
Looking at these set of built-in exceptions:

I can't imagine that being the reason. I just did a fresh clone, and it
was just over 200MB download, and the commit count on the main branch is
less
