Strict definition of value types and reference types

Slices are a small value, that contains in place a length and a 
pointer. The pointer refers to memory allocated elsewhere. So 
slices are kind of hybrids between values and references. You can 
also think of them as fat references. When you program in D you 
must remember this nature of sliced, otherwise your code will not 
work...
