 [@DESCRIPTION@]	Provides a default implementation of the type-classes, required for 'RegEx.ExtendedRegEx' Int.

 [@CAVEATS@]

	In contrast to the traditional regex, there's no reason to escape a 'Char', other than when referring to a /shortcut/.
	Since no /shortcuts/ are defined in this minimal definition, it's always an error to escape a character.
