How to ensure that your program cannot fail ? How to ensure that what you're developing will work as expected without unwanted side-effects ? etc. Since then, several approaches were developed; one of them is static type analysis, a methodology which tries to prove that your program is correct based on the mathematical types theory, whose basic assumption is that unless your program can prove it attends it's basic contracts, it is faulty. Considering Erlang is widely known by it's focus on fault-tolerance and, by consequence, guarantees of reliability, there have been several attempts to improve Erlang programs by proving their correctness with type systems but such attempts have failed. This talk proposes to explain what is a type system, why attempts to type strictly Erlang have failed and how the theory of Session Types might prove to be a way to achieve correctness in environments like Erlang's.
