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 <- dict linear:
		foo set: "key1" "val1"
		foo set: "key2" "val2"
		foreach: foo :k :v {
			print: k . ", " . v . "\n"
		}

	}
}
