It would seem more logical to use .BaseNamespaceEnv.  Today it has the 
same contents as baseenv() (but a different enclosing env), but that may 
change.

I do wonder why you are using this: the R code clearly doesn't.  For base 
is not a normal namespace and is automatically imported into every other 
namespace (or similar words, as 'import' is used in a couple of senses in 
the documentation).
