class desing, but you can't take slices, if you want substring, you make it.
Arays there are always mutable, and how do you really need an array slice? D
strings are char arrays modified with language-level attribute, in .Net String
is a mutable object with immutable content, and immutability is achieved
through class-level implementation. Do we really need const for immutable
strings and do we really need strings to be arrays?
