Yeah, fine -  we have no problem to notice this bug! :-)

My example shout only show, that we have a mix of values and functions,

An example of an unnoticed, critical error-case gave the OP.

You are right. I had made this error maybe 2 or 3 times and found the bug 
fast and without problems.
But because it's a simple "typing error" or so, i am not save to make this 
error again... :-(
