There appear to be a few small bugs (missing closing-parentheses,
different library name) in the code included in SRFI-106 in the Example
and Implementation sections.

Since the code is inlined in the SRFI document, I am attaching diffs
based on the files into which I copied the code.  In any case, a quick
visual inspection of the diffs probably suffices to determine the
changes.

I tested the modified code with Ypsilon 0.9.6-update3 and it seems to
work as expected.
