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.
