Starting with Curl 4.0, you can use 'tuple' syntax to swap values without an explicit temporary value:

Code: 
set (a, b) = (b, a) 

This syntax is also useful to supply default values from a conditional when the other branches produce multiple values:

Code: 
let (x:double, y:double) = 
   {if call-function? then 
       {get-coordinates} 
    else 
       (0.0, 0.0) 
   }
