Is there any way in D to define static methods or members

sometimes help with code organization. For example, this is 
something that coming from Java I'd have expected to be valid 
but isn't:

enum SomeEnum{
    NORTH, SOUTH, EAST, WEST;

    static int examplestaticmethod(in int x){
        return x + 2;
    }
}

int z = SomeEnum.examplestaticmethod(2);

You can't declare functions inside of an enum, however, you can 
emulate the behaviour using an anonymous enum inside of a struct 
or class.

ie.

struct SomeEnum
{
    enum : SomeEnum
    {
        NORTH = SomeEnum("North"),
        EAST  = SomeEnum("East"),
        SOUTH = SomeEnum("South"),
        WEST  = SomeEnum("West")
    }

    const string name;

    static SomeEnum getWithName(string name)
    {
        // . . .
    }
}
