Initialize enum value when calling function

Is it possible to initialize an enum value like this:

enum Test
{
    X = function("X")
};

I am currently getting this error in Visual Studio:

error C2057: Constant expression expected

And Visual Studio doesn't support constexpr

The list of enums in an enumeration declaration is defined as follows:

list-list is a comma-separated list of enumeration definitions, each of which is either just an identifier that becomes the name of the enumerator, or an identifier with an initializer: identifier = constexpr



You can only use constant expressions.
