So much great feature like :
  - null all over the place.
  - Having NUllable and NonNullable in phobos. BTW, NonNullable is 
unable to ensure that it if effectively non nullable.
  - Having to check for .init state all over the place (which have 
a runtime cost, in addition to be error prone). RefCounted 
implementation is emblematic of that.
