In the near future all packages will have a name space. If the sources do

one themselves.
This is great. However, it would also be great if a user could
disable this for a given package at install time, for example with a
command line argument to R CMD INSTALL. Use case: in the early stages
of package development I find it incredible useful to not have a
NAMESPACE. This is of course before I release it to anyone else;
purely for development.
My guess is that this has already been anticipated, but in case not, I
wanted to raise the issue.
I think the idea is to completely remove support for the bad search
order you get when you don't have a namespace. That search order is a
mixed blessing in debugging: it makes it easy to replace functions with
new versions, but it also makes it very easy to execute the wrong code
if you happen to have something sitting in the global environment that
has a conflicting name.
It seems like something a front end could do to make assignInNamespace
easier to use to make working with namespaces easier.
