Indeed: the return value of `defun' even changed recently (from
returning the definition to returning the defined symbol).  Same for
defalias.

I think I'll file another bug report: adding user defined functions to
hooks not only has the common pitfall which is not warned about - the
alternative, using named functions, is also quite inconvenient since
defun's return value is unspecified.  I guess most users currently do it
wrong.  Or do I miss something?


Thanks,

Michael.
