+The typical go idiom is to return an `error` or a tuple of (thing, `error`) from functions. This works well if a function performs exactly one task, but
+when a function does work which can reasonably partially fail, I found myself writing the same code over and over again. For example:
+
+    // CommitBatch commits as many things as it can.
+    func CommitBatch(things []Thing) error {
+        errs := errset.ErrSet{}
+        for _, thing := range things {
+            err := Commit(thing)
+            if err != nil {
+                errs = append(errs, err)
+            }
+        }
+        return errs.ReturnValue()   // nil if there were no errors
+    }
