Another annoying one from that category is Ruby's forwarded methods. Since they're created via generated, injected code, you can't query which method it forwards to at runtime. Or not easily anyway.

`binding.irb` and `show_source` have been magical in my Ruby debugging experience. `binding.irb` to trigger a breakpoint, and `show_source` will find the source code for a method name, even in generated code somehow.

… I’ve been using Ruby for years and never thought to use show_source like this in a debugger. Thanks kind stranger, you just made my day!

Yep yep, that's the whole "sharp knives" thing.

What I advise (and aim for) is only pulling out the sharp knives for "library" code, but application code should stay "simple" (and this much more easily navigable). Otherwise you can absolutely make a bloody mess!
