Sure, but why?  If it's possible to do that, I think we should just do
it always.  It might be a net reduction in readability for people who
don't use overloading but do have functions with very long names and
lots and lots of arguments, but even if you think that's good design,
I think the general principle that an error message should uniquely
identify the object responsible for the error ought to take
