Thx, I was aware of Scott Meyers item (stumbled upon that already in the 
past), but here it can't be seen as a function since 'id' is not a type 
but a variable. The compiler also see 'id' not as a function but as a 
variable declaration of 'Bla'. Is that because u can also declare a 
variable like this:

int (i) = 0;

and why is that allowed?
