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