Hello
I miss the invariant-check during the execution of
the auto-generated ctor.
Following programm ....
**************
import std.stdio;
class ClassA
{
private int mValue;
// with the following default-CTOR would be the invariants be checked:
// this()
// {}
@property
{
public int value() const
{ return mValue;
}
public void value(int newValue)
{ mValue = newValue;
}
}
invariant()
{ writeln("checking INVARIANT ClassA (mValue: ", mValue, ")");
assert ( mValue>0, "NOT mValue>0");
}
}
public static void main ()
{
writeln("creating ClassA");
ClassA aObject = new ClassA(); // may not pass;
// because ClassA has no good CTOR
writeln("reading value:");
writeln(aObject.value);
}
**************
compiled with "DMD64 D Compiler v2.057"
and run will shown this output:
**************

I would expect that the assert should throw an Error during the ctor.
