JosiahParry / r67.R

Created September 7, 2024 16:24

Experimentation with R6 and S7 hybrid. Allows for the creation of mutable objects with type-safe properties as well as self-referential methods.

	# What do i want from an object oriented R class system?
	# opt-in public immutability - neither. Accomplished with private property with active binding in R6
	# interior mutability - R6
	# type safety - S7
	# self-referential methods - R6

	# private methods don't have any type safety they can be whatever you want.
	# immutables can only be set at creation and class doesn't matter

	# Each .public & .private element must be named
