   exp(-x/2)*(-1+exp(x/2))^3 vs. (-1+exp(1/2*x))^3/exp(1/2*x) as an   
   input (via Maple's 'combine' command) for integration and results.   
      
   I agree with acer.   
      
   And accept that it is difficult (or impossible) to have a common   
   normalization for all the CAS, both input/output. For example Mpl   
   usually does use not "simplification" for results - though a user   
   would.   
      
   Anyway: I appreciate your work.
