Just call

        (show-tree)

The result is printed to stdout. You may also use

        (the-buffer)

or

        (tree->object (the-buffer))

I recall that we mainly use scheme as an *extension language*,
because it is convenient to represent "dynamic data" in scheme
(think of the menus or keyboard bindings). I agree that the syntax
is not very pleasant for programming (at the beginning at least).
On the other hand, it is very flexible (easy to create your own
constructs) and the scheme language is really a higher level
language than C++.

I guess that one has to practice a bit the language before
understanding its advantages. I had the same reluctance
as you at the beginning.
