None, even if proclaimed such. Though very few languages are properly
typed. Anyway taking Ada:
declare
X : Boolean;
Y : Boolean := False;
begin
Note, I intentionally take a most elementary type.
X is constructed, but not initialized. Y is constructed and initialized.
The postcondition of construction is: X in Boolean. The postcondition of
initialization is [Y in Boolean and then] Y = False.
Construction operates on the object's type. Initialization does on the
object's value/state.
