If I understand your question correctly, you have two enums of

according to their position, right?
My question was very vague, sorry about that.
In my use case I'd like to map SDL2 keyboard scan codes to my own
game input keyboard codes. The two enums would look something
like this:
```
enum SDL_Scancode
{
SDL_SCANCODE_UNKNOWN = 0,
SDL_SCANCODE_A = 4,
SDL_SCANCODE_B = 5,
SDL_SCANCODE_C = 6,
SDL_SCANCODE_D = 7,
}
enum MY_Scancode
{
KEY_A,
KEY_B,
KEY_C,
KEY_D,
}
```
The two enums are not of equal length, so in the end I just
decided to create an immutable array of type My_Scancode[] where
the index is an SDL_Scancode and the value is the corresponding
MY_Scancode enum member. I'm ok with using some memory for this,
as long as it's as fast as possible.
