String Essentials

An advantage of this approach is that by extending all Collections, slices of random access collections (which are themselves random access and could be passed generically) can be operated on using 0-based offsets rather than arithmetic with the startIndex.

Another example of this unintuitive behavior is in:

Subscripting a Range seems unintuitive

The following is confusing to me, and possibly a bug: print((0..<4)[2]) // 2 print((4..<8)[2]) // Index out of range Worse, print(Array(4..<8)[2]) results in the expected 6 This is an issue because I'm using range[range.count/2] to get middle of a range.
