R devel - Jun 2023 - New behavior when running script in package directory?

Surely this behaviour is just a case of ESS being "too clever",
sourcing
*.R files in special way when it detects that a file belongs to a package
(loading dependencies automatically, etc.)?

The function ss() is defined inside of .ess.source(), which is defined here:

https://github.com/emacs-ess/ESS/blob/5c4ae91cefa5c56fd13b204a9a996825af836a67/etc/ESSR/R/.basic.R#L168

If you think that there is a bug, then you could report it there ...

Indeed.
I have now replied to this CC'ing to  ESS-help at ... instead of R-devel at

It's visible in the mailing list *archives* now:
