   Good example of the difficulties. Nontheless all these can be summarized   
   as Initializers, with optional elements or repetitions, as indicated by   
   the ":" or ",". If required, a finer distinction between the various   
   initializers can be made when processing the parse trees.   
      
   In contrast to C, I never found symbol table information required for   
   properly parsing OPL sources. More problems arise from the semicolons,   
   introduced by unreflected extensions of the Pascal grammar :-(
