Column aliases

I've not had much luck finding a way to alias column names.

(clsql:select
		  [response_date] [comment] [val]
		  :from *comments-view*
		  :where [and [= [survey_id] tool] [null [question_id]]])

I've tried

[response_date date]

but I see no difference in the column names or any error.


How can I do this?
