Thanks for the article!

Small typo in C++ example: const_cast needs type in angle brackets:

void foo(const int *p)
{
    int *q = const_cast< int * >(p);
    *q = 4;
}

THANK YOU ! Just speaking for myself : I have learned a lot.The article is very clear and understandable.
(should be nominated for the "Art of technical writing award")
Well done folks.

Great article !
Shows the weaknesses of C++'s const implementation and
points out D's improvements and advantages.
Very attractive and easy to understand !

Also the need for having 3 different keywords should be clear now.

Hello Walter.

Thanks, a very interesting read. I think the only missing element is a discussion, and example, of the invariant keyword, and how it differs from const. I know you have it explained in this page (http://www.digitalmars.com/d/final-const-invariant.html) but since you mention final, and in the C++ portion you talk about the problems with C++ const that are solved by invariant but not const, then I believe it should be added to show how the "constness" hole is close.

Regards,

Myron.

An excellent article Mr. Bright. It certainly cleared some misunderstandings regarding new const/invariants in DMD 2.0.

Good article!  The link to the article currently doesn't appear on the main D page http://www.digitalmars.com/d/  I've browsed some of the other pages and it doesn't appear there either.
