Erlang & la resilienza con pattern matching e processi

Erlang è un linguaggio a mio avviso sottostimato, che ha parecchie cose da insegnare ai vari Scala/Rust/Java(Script) out of there… In particolare ci sono un insieme di feature di Erlang che prese singolarmente non sono difficili da comprendere e implementare, ma è l’insieme delle idee fondanti di Erlang che lo rende assai diverso dagli altri. …
