// TODO: Support destructors (notice how the dtor has no usages listed).
//        - check if variable is a pointer. if so, do *not* insert dtor
//        - check if variable is normal type. if so, insert dtor
//        - scan for statements that look like dtors in function def handler
//        - figure out some way to support w/ unique_ptrs?
