pragma Wrote:Hi i come from a c# background I would like to write the following code in the according D style but i'm not sure howto do it c# code: void foo(IEnumerable<double[]> data) { foreach (var d in data) { do_some_stuff(d); } } i guess the D equivalent to IEnumerable is Range? how would it look like in D?
Usually there's a little need for a range in such case. IEnumerable is usually used because there's a high need for the List collection so it's used even more often than arrays. Current druntime heap implementation already gives D arrays C# List performance.

What do you mean? Do you mean regarding appends, iteration, or what? Bye, bearophile

What? Of course there is a reason to use a Range/Iterable and has nothing to do with performance. He could be getting his double[] from any number of functions found in std.algorithm, most of whom return their own Range type.
