Unfortunately, this example does not seem to work at all, but for a different
reason:
It seems that using any Python source block with :var header args via :noweb
does not work, as it then behaves in the way, that it merely pasted the included
source block, without first putting in the :var values into the variables. I get
errors about those :var variables being undefined, of course, since they are on
the included source block, not on the including one:
~~~~START: *Org-Babel Error Output*~~~~
Traceback (most recent call last):

This is expected. Noweb includes the src block code without altering it.
See 16.11 Noweb Reference Syntax
We may probably clarify this in the manual. Would it be helpful?
I think it would be helpful. I merely tried Python, because it was at hand and
because I did not find ob-racket in M-x package-list RET and did not have
another Scheme installed. Cannot say, whether others find the behavior confusing
or not, but I imagine I would find it helpful, if it was mentioned in the docs.
