Short answer: use `destroy`. Long answer: don't do that.

https://dlang.org/spec/class.html#destructors

GC is not guaranteed to call destructors, and in fact it may run 
into situations when it can't (i.e. objects pointing to one 
another). Neither does it specify in what order destructors of 
GC-allocated objects are run (when they are run). If you need 
deterministic destruction e.g. for resource management, do not 
use GC.
