In an effort to streamline our NAMESPACE, we moved from blanket 'import(methods)' to specific importFrom(methods, ....) for the objects we specifically needed.
Doing so broke a downstream package, however, which has this directive: importFrom(data.table,`.__T__[:base`) That package stopped installing after the above change. I can get it to install again by adding: importClassesFrom(methods, "[") to our package, but I'm not sure why this would be necessary. I'm still left with two questions: 1. How did we end up with ".__T__[:base" in our exports when we don't do any S4 around '[' in the package (we do export S3 methods on it)? 2. Is there any legitimate reason for a package to try and import such an object? In other words, is breaking this downstream package by not adding the 'importClassesFrom' workaround the right thing to do? I don't see any other CRAN packages with a similar directive in its NAMESPACE.
