We have chosen := to mean assignment in our language.

let mut foo: Int

foo := 1

if toss.
  foo += foo

Implementation Strategy

Create a new AssignStatement node
Adjust the parser and scanner to be able to pick up the new node
Handle AssignStatement in infer() in the type checker

Adjust the parser and scanner to be able to pick up the new node 3. Handle `AssignStatement` in `infer()` in the type checker
