Yes they do. It is not possible to implement the range
functions as non-members.
It's done for arrays via std.array.
Nor have I seen ADL supported in any other
language, despite many supporting generic algorithms.
Which other such languages have templates like D or C++?
I don't think it is a template issue. It's a name lookup issue.
There's LINQ in C#, for example.
I agree that it's not a template issue. It's more of a modules vs
namespaces issue. I think the lack of ADL is not a problem in C#
because everyone can (and everyone does) extend an existing
namespace, so most user's of LINQ algorithms just slap a `using
System.Linq` on top of the file without caring in exactly which
file the functionality they're using is coming from.
Personally I'm glad that D doesn't have ADL because ADL can make
it very hard to find which overload is called.
