The “problem” with ruby is that you basically don’t know if code is valid unless you execute it, whereas a statically typed language will enforce a lot of things during compilation and simply not allow the program to compile, if API is used in the wrong way, this could be calling private functions, referencing undefined symbols (simple typos), wrong number of arguments, passing a string where integer is expected, etc.
Additionally access control is limited in Ruby, which makes it difficult to release a library and have the language enforce that people do not rely on things which are implementation details subject to change.
