open command versus namespace command

Stream: new members

[Seth Chaiken]

How is "open foo" different from "namespace foo" when the namespace it targets had already been created and ended?

I see that under "open foo" (and not in namespace foo) a new name say nnn is not created as foo.nnn.

I see "open foo ..... end foo" fails. Is there any way to stop the aliasing "open foo" does, analogous to "end <namespace_name>?

Enclose it in a section ... end

When open foo is in effect, foo.bar can be referred to simply as bar; it "opens" the foo namespace for use, but not for adding stuff to the namespace.
