My first inclination is not to do this.  The class library is a
library; printing to stderr like this is a bit unfriendly.  It seems
to violate the bounds of what a library ought to do.

I'd like to know more about the situation that lead up to this patch.
I assume you ran into some trouble?  I don't like to say "no", but at
least in this case I need to be convinced.

The wording is fine.
