If I understand this right, you're looking for something like Lua's unpack function. AFAIK you will not be able to do this in Clojure using functions, because Clojure functions can only return one argument. The only way to achieve this behavior would by by transforming your calls using reader macros and then eval. I do not recommend doing this.
I understand that something like unpack is a more general case of apply, but I can't think of any scenario where apply isn't enough - out of interest, what are you trying to do? -Adam On Monday, November 5, 2012 5:45:46 AM UTC+1, cej38 wrote: > > Say you are given a vector A=[a1 a2 a3 a4] by some function/library/Java > call/whatever. > You want to use A in some function F that expects the values a1 a2 a3 a4 > but not in the form of A; for example (defn F [w x y z] (+ w x y z)). > Is there some function G that you can use on A such that (F (G A)) would > give the correct answer? > I now know ways of getting around this, for example in the overly simple > problem I gave above I would use (eval (cons F [1 2 3 4])). > But I have came across problems where I have had to spend a large amount > of time trying to figure out how to do this correctly. > I would think that there could be something to act as G. > Is there something like this?
