Thanks Johannes,
I was aware of the modules package (it was not suitable for my needs
unfortunately), but I did not know about box… somehow I managed to completely
miss it in my search (embarrassing, really).
My own package offers similar functionality to box, but is designed to closely

Hi Greg,
That was my original plan as well, but managing and deploying dozens of little
packages that are all under active development is a nightmare even with
devtools. Just too much overhead, not to mention that coming up with names that
would not have namespace conflicts was getting silly.
Taras,

I have opened a bug report here:
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=18138
Regarding _R_S3_METHOD_LOOKUP_USE_TOPENV_AS_DEFENV_… maybe it’s a good time to
consider purging it alltogether? This behavior appears to be completely
undocumented and this variable is mentioned exactly t
One error in my workaround: it also ignores
_R_S3_METHOD_LOOKUP_USE_TOPENV_AS_DEFENV_. If that evaluates to FALSE,
it shouldn't need to make any changes.
