[llvm-dev] Why StringRef is not a ArrayRef<char>

[Ramkumar Ramachandra via llvm-dev]

I think it's the same difference we have between int * and
ArrayRef<int>, for instance. If you have a raw pointer, you are
expected to keep track of the size out-of-band. In aggregate types,
size is part of the type, making it very difficult to confuse a [1 x
i8] with a [3 x i8]. Many people probably use the raw pointer as a way
to hold a reference to dynamically allocated memory, and as a
type-escape hatch.
