Without encoding information about the type you store, yes, this is indeed impossible in any type system without type sniffing at runtime. It's just static type systems will complain more loudly about it. | |
| Aug 18, 2016 at 11:43 | comment | added | ksl | @DanPantry Ultimately I want to put properties in a map. The key is the property name, which is a unique string. That values of the properties can be different types. | |
| Aug 18, 2016 at 11:12 | comment | added | Dan | why do you need this? Answerers have given you bodgy ways of doing it, but what is your end purpose here? | |

| Aug 17, 2016 at 17:06 | comment | added | ksl | I'm not sure I understand your question about how I know it's a float/String/Integer. The magical class would give me a compile time error if I tried to assign a returned property value to the wrong type (rather than a runtime error). | |
| Aug 17, 2016 at 16:39 | comment | added | Pimgd | Need more context to answer this one; How do you know it's a float/String/Integer right now? What would a magical class that would give you the value already casted give you as benefit? This looks like a design issue to me and I don't see a solution without knowing the use cases. | |
