/**
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

Otherwise, `this` String is split into parts at each occurrence of
