I also like

Yes, I think this is the most frequent case of something
like
if (! args(0).is_string ())
{
error ("...");
return retval;
}
so I think it makes sense to start with this one and see
what we think.
I'll work on this with my other changes.
My current idea is attached. With it, you can write something
like
std::string url = "" ("urlwrite: URL must
be a
string");
Comments?
