[Thomas Sjöland SICS]

I have the opposite experinece of teaching Prolog to people who have an 
experience of Mozart/Oz,
and I can gladly report that some of the more stupid questions I tend to 
get from people who
have only been exposed to Java, C/C++ go away. The main problem these 
students have is of course
to understand the various aspects of Prolog search, the cut and the 
grammar notations as well as the clever ways
in which you can use the syntactic support in Prolog, which has no 
counterpart in Oz.
Whether these features of Prolog really makes it a better language can 
be debated as is nicely done in the
VanRoy Haridi book. Some of my students clearly miss some of the Oz 
features that they have gotten used to,
 though, such as higher orderness, concurrency, scope rules of variables 
etc.
