`colnames<-` is not generic as Luca noted.
But `dimnames<-` is.
If you write a suitable `dimnames<-.myinstance`, then `colnames<-` will
find it.
`dimnames<-.data.frame` gives an example.
I think you will want to either call NextMethod() or replace
attr(x,"dimnames") and return x. That is, you probably do not want to
use `dimnames<-`inside `dimnames<-.myinstance`.
