None of the points you made are specific to ruby. Any language can have technical debt, dangling pointers and so on. I think you might have had the misfortune o

  > Any language can have technical debt, dangling pointers and so on Any language can have tech debt, but I want access to tools in order to help me refactor my way out of that. Working with Ruby feels like building on a foundation of sand with mashed potatoes. It requires a huge amount of discipline to maintain a good enough test suite to combat code rot, and even then, a sufficiently paranoid test suite becomes a hindrance to change (not arguing against tests, just how much extra testing a dynamic lang requires of you if you want to have confidence). You have to refactor incredibly slowly, one small change at a time. Dangling pointers are not an issue in languages like Haskell, and ML. We've had these around for decades. Thankfully most newer languages are banishing them.
