I would genuinely appreciate cited references to back up your assertion that Rails almost certainly does encourage dangerous developer patterns.

I'm not trying to be pedantic; I do hear this sort of claim a lot but when pressed people rarely have anything more than pearl clutching about various metaprogramming capabilities that rarely get used outside of blog posts.

In other words, just because you can redefine + doesn't mean everyone is doing that in production code. :)
