Mutation?! :)

I suppose that these different solutions might hint at some of our 
varying styles or priorities.

My use of "syntax-rules" was done as an exercise, or I probably would've 
used newer features and been more readable.  But, as a matter of current 
personal style, I still would've tried to avoid redundant tests and 
mutations in the generated code.
