/**
	The EReg class represents regular expressions.

	While basic usage and patterns consistently work across platforms, some more
	complex operations may yield different results. This is a necessary trade-
	off to retain a certain level of performance.

	EReg instances can be created by calling the constructor, or with the
	special syntax `~/pattern/modifier`

	EReg instances maintain an internal state, which is affected by several of
	its methods.

	A detailed explanation of the supported operations is available at
	<https://haxe.org/manual/std-regex.html>
