I'd like to filter a range and then change the filtered

I guess I could create duplicates, but I would like my changes
also to be reflected in the original range.

It doesn't. It returns front, and by Ref if at all possible too.
//----
void main()
{
auto arr = iota(0, 10).array();
foreach (ref e; arr.filter!"a%2"())
--e;
writeln(arr); //duplicate evens
}
//----
[0, 0, 2, 2, 4, 4, 6, 6, 8, 8]

There must be something else that is wrong. What are you trying
to do?
