nit: This is not actually used in the header.  I'd prefer that you remove it
entirely -- IMO this sort of typedef hurts readability more than it helps.  But,
if you decide to keep it, please either use it in the header, or move it to the
implementation file.

Removed, just a holdover from previous IE based implementation.
