You are right: I was not looking correctly. :-(
In a way it is even better, because it also gives the namespace.
The only 'bad' thing is that the function name comes after the parameters,
but with rewriting the error message and becoming used to it, that should
not be a problem.
Still it could be useful for log messages to get the function name. So I
will look into the other replies.
