Not reporting a bug when you run into it but instead just complaining about it is in fact lack of competence. Arguably using super-sparse arrays in JS is also lack of competence, but the other is much more obvuous. > It's a basic question of what level of resources you are willing to put in Filing a bug takes about 5 minutes.
