It seems I misunderstood the original request and got it backwards - but  
then I have to question the usefulness of doing so. If an error happens in  
the "decorating" function (as opposed to inside the function being  
decorated) I'd like the error to be reported as such, in the "decorating"  
function (else tracebacks and line numbers would be lying).
