Erlang has single-assignment variables

“Erlang has single-assignment variables. As the name suggests, they can be given a value only once. If you try to change the value of a variable once it has been set, you’ll get an error.”

(“Single-assignment variables” are the same as val fields in Scala. Using them can make your code more like algebra.)

Used someone else’s.
