Warning regarding error when calling from package code.

[krlmlr]

assignInNamespace should not be used in final code, and will in future throw an error if called from a package. Already certain uses are disallowed.

This warning has been around since 2011, apparently without any action: wch/r-source@91f910d.

I wonder if we should at least hide the call to assignInNamespace() so that it's more difficult to detect with automated checks.

Tbh, I was expecting a bit of pushback when I submitted to CRAN. But I pointed out in my cran-comments.md that I'm using utils::assignInNamespace() and they were fine with my reasoning. I do not have a lot of experience with this kind of issue though. Does it happen often that they change their minds on things like that?

Interested to see how this turns out if you use assignInNamespace - I've been wanting to use it in some pkgs, but just assumed CRAN wouldn't accept a pkg with it. Odd there's so many pkgs on CRAN using it if it's not allowed
