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