Ah, that's an interesting idea, though it assumes they are of the  
same mode (admittedly, in my example they are, I should have made up  
an example where one of them is a character vector).

I had tried something similar, namely x+0*y, but that only works if  
they are both numeric and further the length of y must be a multiple  
of length of x to avoid a warning.
