True. I plan on adding checks that forbid you to do certain things in
autoload files, and defining other functions should be on that list.
Unfortunately, there are reasons for not completely forbidding
everything except function definitions. For example, fish uses
different definitions for the '_' function depending on whether
gettext is installed. ('_' is used to translate a string to the
current language) It makes sense to put this test outside the function
definition.
