I've found it useful to use typedefs for all sorts of things like this. 
Looping through a FooArray with a FooIndex is much more robust than using
a long or something.

This is reasonable for C, but these days I find myself using auto_ptr and
my own auto_array templates to deal with this problem.  On the other hand,
it could still be useful inside a class that used an array to represent
something (e.g. a string).
