  23 # tests for whatis command on expressions.
  24 # used in file eval.c. This flavor of whatis
  25 # command performs evaluation of expressions w/o actually
  26 # computing the value, but just the type
  27 # of the result. It goes through the evaluate_subexp_standard
  28 # with the EVAL_AVOID_SIDE_EFFECTS flag rather than EVAL_NORMAL
