One of the most difficult things for programmers to graft these days is 
the concept and proper use of types, which is key to Ada.  Ada makes 
this even more complicated with the very useful attributes of private 
and limited types.  Unless a text clearly conveys the use of types and 
illustrates it throughout, it is useless for teaching people Ada.  Since 
this is a foreign concept to most current programmers, illustrations and 
good exercises are needed, too.

Compare this text to Barnes, which most of us use as a quick reference.
