You don't need the "else" there. An equivalent:

    def search_in_iterable(key, iter):
       for item in iter:
           if item == key:
               return some_function_of(item)
       return not_found_default


I'm not sure I understood what you meant but I'll assume that by
"plausible"/"reasonable" you meant that it's a good example as to how
for/else is misleading.

On this issue I'm worried about all sentient programmers.
