He said use lazyLoad, not library. It works for me:
env <- new.env()
lazyLoad('R/foo', envir = env)
dump(ls(env, all=TRUE), "foo.R", envir=env)
and BTW this is not going to work if S4 objects are involved and if
the package had a namespace you'll need the NAMESPACE file (or try to
recover that from the metadata).
