Gotcha. The book I have Tcl/Tk by Welch has examples of namespace w/o the
'eval'. Is the book wrong? It says it describes Tcl 8.0. I just want to
know what Tcl book to recommend to customers.
Here's what I'm trying to do with namespaces; maybe someone has an
alternative that would work better: The application I wrote allows users to
open multiple "documents" (I use the term generically here) that may contain
Tcl vars and procs specific to the document. Since there's only one interp
these vars can conflict leading to inconsistent results. I thought that
perhaps the namespace feature would be useful in this situation. However,
I'd like to avoid the user from having to understand namespaces by hiding
them as much as possible. Some questions then...
1) Can variables be exported from a namespace in addition to procs? This is
to avoid having to explicitly say "foo::var1".
2) Is there a way to switch to a namespace so that all evals after then take
place w/in that namespace? I suppose I could simply wrap all user input in
"namespace eval foo { <user input> }".
