Added "value" method to option value and option none. It behaves similarly to value:none, except the none case just propagates the none value and the value case wraps the result in an option value

#{
	main <- {
		foo <- :n {
			if: n < 10 {
				true
			} else: {
				foo <- :n { n }
			}
			foo: n + 1
		}
		print: (string: (foo: 0))
	}
}
