/**
	The basic String class.

	A Haxe String is immutable, it is not possible to modify individual
	characters. No method of this class changes the state of `this` String.

	Strings can be constructed using the String literal syntax `"string value"`.

	String can be concatenated by using the `+` operator. If an operand is not a
	String, it is passed through `Std.string()` first.

	@see https://haxe.org/manual/std-String.html
