Consider including package name in S3 class name(s)?

[rogiersbart]

Since the renaming of the {scales} S3 class to "transform", it clashes with e.g. {raylibr}'s S3 class. The print() method is defined in both packages, and generates a warning, but certain methods from {raylibr} not defined in {scales}, break {scales} and therefore {ggplot2}. In the reprex below, in particular, S3method("$",transform) from {raylibr} is responsible. As {scales} and {ggplot2} are widely used, and it seems to be recommended to include the package name in S3 class names (well, at least according to Advanced R), maybe it would be useful to consider including the package name in the S3 class names? I'm not sure how straightforward this would be however, as I believe most of {raylibr}'s code was generated automatically to wrap {raylib} through {Rcpp} ... ?

library(raylibr)
#> 
#> Attaching package: 'raylibr'
#> The following object is masked from 'package:base':
#> 
#>     transform
library(ggplot2)
#> Registered S3 method overwritten by 'scales':
#>   method          from   
#>   print.transform raylibr
ggplot2::ggplot(cars) +
  ggplot2::aes(speed, dist) +
  ggplot2::geom_point()
#> Error:
#> ! `transform` has no property transform.
