Correct. Perhaps parent comment meant "unstable" in the sense that it turns compile time failures into runtime ones: e.g. without reflection, if you type "customer.GetOrders()" then it either compiles or does not, whereas reflection code that finds a method called "GetOrders" can compile just fine but you won't know if it finds a method of that name or returns null, until runtime.
