Types

Primitive types

Type	Description
`int`	64-bit signed integer
`bool`	Boolean (`true` / `false`)
`string`	Managed immutable UTF-8 byte string
`null`	The null literal; assignable to any reference type

Any non-void element type can form an array: T[].

Arrays are created with new T[count] and have a .Length property.

int[] values = new int[4];
string[] names = new string[2];
int len = values.Length;
values[0] = 42;

Strings support concatenation with + across string, int, and bool operands:

string msg = "Count: " + 42;
string flag = "Enabled: " + true;

String length:

int n = someString.Length;

String indexing is byte-based in the current bootstrap:

string ch = someString[0];   // single-character string

void is the return type for methods that do not return a value.

Hylang currently supports:

Class and interface values are reference types, so null is valid and derived classes can be used anywhere a base class is expected:

Animal value = new Dog();
Animal maybe = null;

Structs use bootstrap by-value semantics:

Point p = new Point(2, 3);
Point copy = p;

var is also supported for local variables when an initializer is present:

var box = new Box<int>(42);
