No, there isn't. C is an unsafe language, so if you want to
call C from `@safe` code, you have to do the work to make sure
that each individual call is `@safe`.

I saw the new feature called ImportC, it's cool to be able to use
C code/libraries, but I'm not much experience in C and didn't

Did you try
BaseItem[] GameItems;
GameItems ~= new
