Uninitialized variables are not an option, so default initialization 
and/or some flow analysis unfortunately seem to be necessary given the 
limited nature of D's lexical scoping rules. The issue is that every 
user-defined type is by default assumed to have a default state. It's 
null pointers with extra steps. I'm not a big fan of the possibility of 
accidentally hiding a type's `init` using a user-defined field, but this 
is a lesser issue and at least this way it can be @disabled, though I am 
not absolutely sure that this completely denies access.
