I'm pretty sure loading the exported symbols of global variables 
works the same way, they'd just be pointers to data instead of to 
code.

```d
__gshared int* foreignLib_some_integer;

//to load:
foreignLib_some_integer = cast(int*)loadSymbol(foreignLib, 
"foreignLib_some_integer");

//using in your code:
if(*foreignLib_some_integer == 10){
   //etc.
}
```
