how do I, in c++ speak, do the D for...

I'm sure this must be trivial.
Many many thanks,

Ah, damnit, Andrei beat me to the punch!
Well, at least his methods make much more sense than my little hacks.

It's a shame we can't use .dup. It would look really nice in code.

Copying classes is not a so common need in D. As an example, I need a byPair()
method for AAs more than dup for classes :-)

What about this feature in Object under name "copy" or "dup"? Sure, it's
not to be used evereday; but it's typcally the kind of routine that,
when needed, we're v

Sure, but wh
Theorizing: Would it be a bad idea if .dup for classes did the same
thing as normal assignment did for structs with postblit constructors?
Essentially I was thinking that code like this would do the trick:
import std.stdio;
class Widget
{
int integral; // field-by-field assignment
int[]
