I have used Nexpert to build a large and complex tool for cpu instruction
failure debugging. 
I my opinion Nexperts most powerful feature is its inheritance
mechanism, which allows for multiple inheritance of: values,  code for determining a value,
general functions for these objects etc.  
I can see that the comment regarding the editors used in the graphical interface may be
too simple-minded for your basic programmer who would rather use VI. 
There are short-cuts for using the editor.  Like key word completion (type just the necessary
characters to denote a particular keyword),  syntax checking,  dependancy checking,  automatic
creation of needed simple structures, and more.

The comment about not seeing anything in the current rule and current hypothesis is stupid.
There is a pop-up window that allows the user to turn on writing to these windows.  
There is a reason they are not always on.  Performance.   
            
I could go on, but I'm not sure anyone really wants to know more......

Please send email to augs@cray.com if you have some specific questions/misunderstandings.
