Yes, I know that it varies from language to language.. but AFAIK modern 
languages tend to short-circuit evaluation - at least Oberon uses it ;)

I never claimed that short-circuit evaluation is more logical - I think at 
first sight the current implemenation is more logical. But all the same I 
believe that there would be an advantage of changing it.
