You don't. If the class has a clone method (which would fairly typically be
called dup in D), then you can clone it, but classes are reference types, not
value
well, they we're interfaces and it made sense to implement them as a
class. On the other hand, a struct is way more efficient and works
just as good. Thanks for clearing everything up.
so would it be wrong to make movefront simply change the index the
front is pointing at without removing a prime?
And I'm coming from a java world so it would make sense to me to
create that range as a class that implements a range but in most
examples I see everyone using structs instead. what

In your case, I don't think you really need to define a moveAt.
opIndex is what's required for a Random Access Range and it
really doesn't make sense to define moveAt for your particular
problem.

moveFront is used to move the front of a range for stuff like swap, when

element isn't there anymore when you do that.
I mean that the value isn't there. The ranges
