Talking about labs, is there an easy way to run (all the sentences of) a lab in immediate execution mode? For example, if I insert the sentence 'u + v' in the 'A J Introduction' lab after 'x+y' and run the lab from a scratch session I get:
x=:2 y=:3 x+y 5 u+v |value error: v | u+ v |[-5] But if I type directly 'u+v' directly in the session I get: u+v u + v I would like this and similar sentences in the body of a lab to exactly match the direct session behavior. Is there an option, easy trick, etc. to accomplish this?
