+1. Function parameters:
+
+ sum :: (a: int, b: int) int { return a + b; }
+ foo :: () { x := sum(1, 2); }
+
+2. Multideclarations:
+
+ a, b := 1, 2; /* Multiple assignment */
+ r, g, b, a: u8; /* Type cascading */
+ x, y, z: i8 = …; /* Multiple undefined assignment */
+
+3. Strings and arrays:
+
+ hello_utf8 := "Hello World";
+ hello_utf16: u16 = "Hello, World";
+ hello_utf32: u32 = "Hello, World";
+
+ X :: 3;
+

+ ys := [X]int{1, 2, 3}; /* Explicit length */
+
+ /* Assign specific indicies */
+ zs := […]int{
+ [2] = 123,
+ [4] = 321,

+4. Conditionals:
+
+ if x > y {

+ …
+ } else {
+ …
+ }
+
+ /* Shortform */
+ if x > y
+ foo();

+ …
+ case 1;
+ …
+ fallthrough; /* Explicit fallthrough; implicit break */

+ …
+ default;

+6. Loops
+

+ /* Shorthand syntax */
+ loop

+ loop x > y … /* While loop */
+ loop x: xs … /* Range/for loop */

+7. Multiple return values from functions
+
+ swap :: (x, y: int) int, int { return y, x; }
+ x, y := 1, 2;
+ x, y = swap(x, y);
+
+ /* Note that this is a function that returns a function! The
+ returned function is one that takes an int and returns nothing */

+8. Default parameters
+
+ foo :: (x, y: int, flags: Flags = 0) { … }
+
+9. Variadic parameters
+
+ foo :: (xs: …int) {
+ for x: xs { … }

+
+ City :: struct {
