Results of evaluation:

(foo1) ==> "Foo1"
(foo2) ==> foo3 ?
(foo3) ==> "Foo3"

Why do you think there's anything wrong here?  AFAICT, each evaluation
returns the last sexp evaluated in the respective function.  foo1 and
foo3 have a call to 'message' as the last sexp, so they return the
message string, but foo2's last sexp evaluates a defun form, so you
get the result of that, which is the function foo3.  IMO, this is
expected and correct behavior.


Basically these forms were made to display a beginning-of-defun bug.

See tests in previous posts.

What puzzles me when evaluating:


(setq a (foo2))
a ==> foo3
(call-interactively 'foo2) ==> foo3

But M-x foo2 RET messages "Foo2"
