23555	QuerySet.first suppresses internal IndexError exceptions	Artem Rizhov	nobody	"Current implementation of this method relies on `IndexError` when checking the item existence. However this exception may be raised somewhere inside of own `__getitem__()` which does a lot of work. This way the potential errors are hidden. The method will return `None` in case of a bug that raises `IndexError` internally. The Zen of Python says ""Errors should never pass silently.""
