Does your hobby language has static or runtime check to catch access to =
 =

uninitialized variables?

I don't see the point with deferred initialization, it seems to be an  =

object state finally (states, again). Either you can tell a variable was=
  =

or was not initialized, and then it has a state and it is finally  =

initialized before you suppose it is, or else it can't tell the variable=
  =

was not initialized because it really initialize nothing at the  =

declaration, and then it's perhaps unsafe.
