Variables & Math

int count = 10;
double rate = 5.5;
boolean active = true;
string msg = `Items: ${count}`;

Structs & JSON

type User { string name; int age; }
User u = { name: "Alice", age: 30 };

json generic = u;             // Implicit upcast
User specific = generic as User; // Explicit downcast (validates at runtime)

Functions & UFCS

int calculate(int a, int b = 0) { return a + b; }
// UFCS usage:
int result = 5.calculate(10);

Control Flow

if (count > 0) { ... } else { ... }

for (int i = 0; i < 10; i++) { ... }

int[] items = [1, 2, 3];
foreach (int x in items) { ... }

Streaming & Errors

yield "Progress...";

try {
    throw "Oops";
} catch (err) {
    yield err;
}
