I agree. There was at one time a D implementation on .net, but it
suffered from .net's lack of support for pointers, which meant that
slices performed poorly.
So how are C++ and C# pointers done in IL ?
There are two kind of pointers in C#: managed and unmanaged. Wrapped in
a fixed statement (just to tell the garbage collector to keep fixed
references), C# pointers will behave like any native language pointer.
This is not the first topic where I read that misconception that slices
are a problem for IL. From .net 2.0 (9 years ago) there is the
ArraySegment<T> type doing exactly what D slices do. Also, in C# arrays
are implicitely convertible to pointers.

I know .NET since the early pre-Beta days as my employer at the time,
had the privilege to be one of the few Microsoft Partners in Portugal
with access to the technology.
In those days I did some C# <=> C++ integration work by means of Managed
C++, later superseded by C++/CLI. Hence my question. :)
