I looked at the `/usr/include/dmd/druntime` folder with `grep 
finalize -r`, and it brought me only one file, that is 
`object.di`.

When I check `object.di`, I see that rt_finalize is defined as 
`extern(C)` and it is called in `destroy` function. Thereby, it 
is defined by the DMD itself. So, there is a `finalize`, but even 
I am not doing anything special in the code, it is not finding it 
while having it in a normal programme.
