After requesting a function call here:

http://localhost:8080/wiki/Special:EvaluateFunctionCall?view=zobject-editor

the results are displayed by ZResponseEnvelope.vue. The presentation should be improved as follows:

• If there is no result (Z22K1 is void), rather than displaying "Reference to void", display an internationalized string such as "No result".
• If there is an error, consider showing a more readable presentation of the error inline, such as that produced by mixins/portray.js (after that code handles all error forms, per the related ticket). Then remove the error bullet from the metadata dialog.
• Consider whether "metadata" or some other term, instead of "metrics", on the Show Metrics button
