Oops, I meant expand-to-top-form :-(

My point was that the information that is displayed is
similar to the information displayed when you do a
(syntax-object->datum (expand '(some-macro
some-params))) while I think a more meaningful
expansion would be the result of (syntax-object->datum
(expand-to-top-form '(some-macro some-params)))

When I click around in the expansion, the "Source" in
the right-hand side is always either colorer.ss or #f.
Can you suggest some source file in the PLT collects
directories that I can load that will show some other
value in "Source"? What is "Source" meant to represent
anyhow? I thought it would be the source file where
the macro is defined.
