Becoming an impenetrable balls of mud also depends a bit on the language design. For example in Python one can implement how objects respond to operators (double underscore stuff), but that hides the characters of the object. In other languages one has separate functions for doing things with different types like string-length, vector-length, and so on. When you see that in the code, you immediately know the type of that argument of the function, because it is explicitly in the name of standard library functions. It is a language design choice.
