Here's all the cases for using a semicolon. (estimated 30 seconds read) 1. At the end of local variables let a = 1; b = 2; in a + b result: 3 2. At the end of each attributes in an attribute set (a.k.a. dictionaries or key-value pairs) { a = 1; b = 2; } result: { a = 1; b = 2; } 3. with expressions with pkgs; coreutils result: (the coreutils attribute in the pkgs attribute set) 4. Assertions assert a != null; a result: (the value of a) Now, you'll never be confused again.
