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.
Anyway, I don't see any use for a D IL compiler, since probably
the language syntax will look 90% like C#.
