What is an idiomatic way of representing enums in Go?
... literal value 42, which the function would accept as base since it can be casted to an int. To prevent this, make base a struct: type base struct{value:int}. Problem: you cannot declare bases as constants anymore, only module variables. But 42 will never be cast to a base of that type.

Create a new object from type parameter in generic class
...r, even in JavaScript. If you have a class Foo{ method() { return true; }, casting {} to T will not give you this method!

Function overloading by return type?
...le, in C++, the overload would likely have been resolvable using some ugly cast syntax.

How to Sort a List by a property in the object
...
One must first test for null on the as cast. Which is the whole point of as, as (ha, ha) (Order)obj throws an exception when it fails. if(orderToCompare == null) return 1;.

How can I order a List?
...in a List<string>, you can either change its declared type, or use a cast. If you're not sure, you can test the type:
if (typeof(List<string>).IsAssignableFrom(ListaServizi.GetType()))
((List<string>)ListaServizi).Sort();
else
{
//... some other solution; there are a few ...
Is there a way to iterate over a slice in reverse in Go?
...rface{} will not take a []string as input anymore. Even if string can be casted in interface{}, []string cannot be casted in []interface{}. Unfortunately, the present reverse function is the kind of function that needs to be rewritten a lot.

How different is Objective-C from C++? [closed]
...Objective-C is a more perfect superset of C. In C and Objective-C implicit casting from void* to a struct pointer is allowed.
Foo* bar = malloc(sizeof(Foo));
C++ will not compile unless the void pointer is explicitly cast:
Foo* bar = (Foo*)malloc(sizeof(Foo));
The relevance of this to every da...
Pass data to layout that are common to all pages
...u need for the layout, why bother adding it to the ViewBag only to have to cast it back again? Use the model in the layout view, you can still populate the model in OnActionExecuting. Using ViewBag also means you loose type safety in your controller, never a good thing.

Why is Dictionary preferred over Hashtable in C#?
... because you can't insert any random object into it, and you don't have to cast the values you take out.
Interestingly, the Dictionary<TKey, TValue> implementation in the .NET Framework is based on the Hashtable, as you can tell from this comment in its source code:
