That is my impression too. I find that the most relevant metric impacting the bug density is number of lines on this one project, and it's very non-linear.

That puts at advantage both languages that reduce line count, and languages that make it possible to abstract the plumbing into a generic library (if it's not generic, it's part of this one project). I think mostly everybody has that same impression.

Still, we shouldn't pretend that impression is a scientific certainty.
