Hi, I have a basic question about writing a compiler using conti   
   uation-passing style   
   as an intermediate language.   
      
   It seems to me that if one performs the cps transformation one is left   
   with many 'computed' calls (that is call to variables holding   
   procedure values, namely, the continuation). It seems that compiling   
   such 'computed' calls would be much slower than compiling 'direct'   
   calls to known procedures.   
      
   Question:   
      
   1. Is this assumption valid?   
   2. If it is, then it seems that cps is not very useful without some   
   non-trivial control flow analysis...??   
      
   Please excuse me if this question is very basic.   
      
   Thanks!
