I personally don't mind anonymous functions, I use them when I can fit 
everything on mostly one line and they don't have any side effects. 
None of my decorators that I write actually call the function they are 
passed either.

So there could be a lambda statement...

     lambda employee:
         if employee.developer and employee.not_using_python:

...which would make a function that isn't named, purely for its side
