Hi and thanks again for taking some time to help. Although I allready
knew how to get the *real* result… thanks to your answer to my first
thread.
Here, I did not put this "echo function('s:objFuncs.form1/2)" to get
the real result, but just to illustrate the fact that, to me, form1 and
form2 seems to be equivalent :

So I (still) wonder why some real developpers would use form2 (the non
anonymous version) rather than form1 ? I hope this claryfies my question
and that I understood your answer correctly. ^^
Best regards.
