Hello,
I am looking for something like the "Iterator" Interface in Java or PHP.
Is there something comparable in D that can be used with foreach?
Thanks,

opApply if you want 0 .. N iterations during for a foreach statement and
having it reset each time.
Otherwise you want ranges :)
An input range is more or less an iterator as you would think of it.
You only need popFront, front and empty. But here is the "official"
interface. http://dlang.org/phobos/std_range_interfaces.html#InputRange
You can have structs an an input range, it is quite common since it
doesn't allocate.
