Thanks. I obviously was "perhaps" wrong ;-)
Now I get a better understand about why callable's [] is
equivalent to .call() ! They really look similar.

I knew there was a bug in my code because I had applied
Sherlock Holmes' method:
"Eliminate all other factors, and the one which remains
  must be the truth." -- The Sign of the Four
I just could not see it.
Thanks again.
