D's slices are "fat pointers": In D's case, that translates to a pointer 
plus length.

Agreed. Pointers are fundamental features of CPUs.

That is not correct. Slices are designed by a C expert to prevent 
horrible bugs caused by C experts. Most C experts use slices very happily.

That is an old thought. Today, we see that no matter how experienced, 
every person needs and appreciates help to prevent bugs. There are many 
cases of bugs killing people, jeopardizing expensive projects, loss of 
personal information, etc.
