[plt-scheme] Difference between 'send' and 'send' in an eval?

Hi.

Thank you for your reply.

Unfortunately, the code doesn't work. It seems that I run into the same
problem of the code not understanding that the object in the eval code
refers to the same object outside of it. Here's what I learned from
Matthew Flatt: What's going on is that both environments are dealing with
the object from two different class mechanisms. Using
"namespace-attach-module" does the trick.

Thank you for helping me. :-)
