Because "copy" is still modified every time "i" is.
But shouldn't copy be redeclared every loop iteration (or
the compiler could pretend to redeclare it).
No, it will have the same address every time.
The current behaviour is wrong:

These are slightly different problems. I think Freddy's
programs are working as designed.
D closures should work in the same way as, e.g., JS closures.
Try rewriting the program in JavaScript. If it behaves in the
same way, it's not a D bug.
I don't think so. JS is not comparable, because it's scoping
rules are different from D. Closures should capture the variable,
not its memory location. And both `i` and `copy` are distinct
variables in each loop iteration, they just happen to share the
same location, because they have non-intersecting lifetimes.
