Re: [Agentfactory-developer] Active Actions

[Marc-Philippe H. <Mar...@un...>]

I agree with David that I prefer something like:

?x = .println("rem") // single value
[?x,?y] = .coords("rem") // list

maybe it is time to remove dust from some of our books on functional programming especially Lisp and Haskell...

Cheers,
mph
