-    > function isEven( v ) { return v % 2.0 === 0.0; };
+    > function f( v ) { return v % 2.0 === 0.0; };
     > var x = [ 1.0, 2.0, -3.0, 4.0, -5.0, 6.0 ];
-    > {{alias}}( x.length, x, 1, isEven )
+    > {{alias}}( x.length, x, 1, f )

     // Using `N` and stride parameters:
     > x = [ 1.0, 3.0, 4.0, -5.0, -6.0, -3.0 ];
-    > {{alias}}( x.length, x, 2, isEven )
