  30. Where in the working papers does it say this?  They appear to me to be
  31. introduced in 14.8 [temp.arg], which as far as I can tell applies to
  32. both functions and classes.  I see nothing in 14.10 [temp.fct] which
  33. disallows them--what did I miss?
  34.  
  35. Why are they disallowed?  Are there any technical difficults?
  36.  
  37. Thanks,
  38.
