Neither was Prolog.  It is used for useful programming as well as 
education (e.g. teaching unification to students).  It isn't 
suited for programming-in-the-large, but that doesn't make it 
useless. And to be frank D's symbol resolution isn't suitable for 
programming-in-the-large either.

Of course, Prolog is old and there are also other alternatives 
for various types of problem solving, but the fact that almost 
every CS student have some understanding of Prolog unification 
makes it very influential.
