Hi,<br>
<br>
If I have a function that produce tuples with three members and I want those members as parameters for a function that takes three parameters.<br>
How would I unpack that tuple?<br>
<br>
It seems that curry does the trick for tuples with two members.<br>
<br>
How do I do this when there are more than two members?<br>

There are functions like 'curry3' ( <a href="http://hackage.haskell.org/package/utility-ht-0.0.14/docs/Data-Tuple-HT.html#v:curry3" rel="noreferrer" target="_blank">http://hackage.haskell.org/pac<wbr>kage/utility-ht-0.0.14/docs/<wbr>Data-Tuple-HT.html#v:curry3</a> ) but I think if you don't need this very often, it might be easiest to just go for<br>

let (a,b,c) = f x in g a b c</blockquote></div></div></div><div dir="auto"><br></div><div dir="auto"></div><div dir="auto">Ok, so in general I would have to write the unpacking myself. Correct?</div><div dir="auto"><br></div><div dir="auto">// Patrik</div></div>
