digitalmars.D.learn - File IO: C# streams VS iterators?

Walter said he thinks iterators (unless I remember wrong) is 
superior. The speaker agreed but said it isn't a drop in 
replacement so that is an issue if you want to port.

I haven't access file in D and i'm completely confused. What are 
iterators in regards to file IO?

There are several ranges that can be used for file IO, for example 


such capability, which is why you have TextReader and TextWriter on top 
of streams, etc..

However, sometimes it's useful to have polymorphism for accessing 

would be pretty trivial to port the base classes to D and implement them 
using the D ranges.

For that, there's Tango:

he must have said ranges. A range is like a pair of iterators. It's 
heavily used in D.
