Why is this an error. Dmd wants to make sure that I declare a new
variable in the foreach statement and not use an existing one?
module test;
void main()

int i;
int[] nums;
foreach(i; nums)
{
//
}

dmd test.d
test.d(7): Error: shadowing declaration test.main.i is deprecated
Yes; as the error states, you're not allowed to define variables with
the same name as variables in an enclosing scope any more.

Why does it still work for some objects?
This works:
module test;
class A
{
this()
{
//
}
}
class B
{
this()
{
//
}
int opApply (int delegate (inout B) dg)
{
return 1;
}
}
void main()
{
A a;
B b;
foreach(a; b)
{
//
}
}
It is a bug and should be reported.
