end

type ExplicitFruits

int BANANA = 20

int CHERRY = 1

end

type Main

 

The only way to give such a variable a value without setting it explicitly is to add one to the previous such variable which (in effect) is what a C-style enum does. If you declare a variable in Wren without giving it a value, then it is set to the special value ''null'' which is no help here.

var ORANGE = 2

var PEAR = 3
