Hey Brad,
his is a good point. I myself discovered the displayName trick back when reading Thomas Fuchs’ excellent JS Performance Rocks book ( http://javascriptrocks.com/performance/ ).
It is probably worth mentioning; I need to check what the current status of implementation across browsers is, for that. Still, using NFE’s (named function expressions) when declaring methods remains a good practice, although it would indeed become cumbersome for functions-as-blocks use-cases.
Best,
