Is there a way to reproduce your problem with one of the S3
methods/generics in default R packages?

I am not using S3 myself and, quite frankly, I have already forgotten
the exact caching mechanism of S3 methods. Also this mechanism might
have been changed in 3.0.0, so a reproducible example would be very much
