+### set*
+
+Allow parallel mutation of multiple mutable variables.  (All right
+hand sides are computed before setting the left hand sides.)
+
+```
+# you can use it with vars
+(var a 2)
+(var b 3)
+(misc/set* [a b] [b (+ a b)])
+[a b] => [3 5]
+
+# or you can use it with arrays, for example:
+(def x @[2 3])
+(misc/set* [[x 0] [x 1]] [(in x 1) (+ (in x 0) (in x 1))])
+x => @[3 5]
