The variables we're talking about here *are* initialized. They contain
valid values and none of the internal RTL routines will crash when used
with them. Everyone however expects result variables of those to be
initialized to Nil and that is simply *not* a guaranteed given.
Also records only initialize their managed fields. All others are left as
garbage.
