What happends if we will ignore const/immutable modifier for
postblits? Is it create any holes?
it will break "const promise". i.e. "const/immutable data is
not really
immutable now, it can be modified".
It's just common words=)
I meant that when postblit is called when new object is being
creating and doesn't exists for user code.
E.g.
const S v1 = v2;
Ok, v1 _will_ be const when it will be _created_.
However postblit can think that object is mutable, because it
called before the first accessing to the object from user code.
Thus I ask about case when postblit may mutate a const object,
which created before postblitted object and may been accessed
from user code before this postblitting.
