Hogwash.

Goto the text widget overview and grep for:
Most text manipulation is accomplished with iterators....

It covers the essentials:
1) logically, an iter is a position between to characters in a buffer
2) the underlying data structure is designed for stack allocation and
   copying.
3) its short lived, modifying the buffer could make it invalid.

As for the utility of an Iter, you will notice that they are used to a
great extent in the API of TextBuffer and View for communicating a
specific location in a TextBuffer.
