  11. Hi !  This seems dumb to the extreme, but I am stumped.
  12.  
  13. How does one write a function/macro/anything to return the input, like the
  14. old nlambdas and fexpers used to do?  The reason:  I'd like to track what I
  15. do without having to quote everything.  Say, track-it, which returns the
  16. value of foo, but pushes the symbol foo onto a list:
  17.  
  18. (setq bar '(a list with data))   (defparameter *all-new-names* '(some old
  19. names too))
  20. (track-it bar) --> (a list with data), and   *all-new-names* = (bar some
  21. old names too)
  22.  
  23. Thanks
