-## After < 0.6.0
+## Example with error handling
 
-Older versions of after had iterators and flows in them.
+```js
+var after = require("after")
+    , next = after(3, logError)
 
-These have been replaced with seperate modules
+next()
+next(new Error("oops")) // logs oops
+next() // does nothing
 
- - [iterators][8]
- - [composite][9]
+// This callback is only called once.
+// If there is an error the callback gets called immediately
+// this avoids the situation where errors get lost.
+function logError(err) {
+    console.log(err)
+}
