  22. Agreed. C++ makes a lot of things easy to do including:
  23.  
  24. 1. Passing large objects by value.
  25. 2. Creating temporary objects as a result of silent conversions.
  26. 3. Creating new code as a result of template instantiation.
  27.  
  28. It's very easy to build large programs that require lots of memory and
  29. that run very slowly.
