In almost all dynamic languages I know of for example. Way too easy to forget about error handling if you use values. Exceptions at least tend to cause noise.

In almost all dynamic languages I know of for example. Way too easy to forget about error handling if you use values. Exceptions at least tend to cause noise. In languages like Java an Python, you can return error values but because you can also always return nulls, you're just making more trouble for yourself than it's worth avoiding exceptions.
