Restructured print_code() to use Macro.prewalk/3 (First of two offending functions)
Removed unused function (Second of two offending functions)
I did not see the function (or it's associated private functions) being used anywhere and I did not know how best to test it since I could not determine what its purpose was for - so I opted to just remove it rather than restructure the code as I previously did.
If this leads to trouble down the line, we can always revisit and reimplement with a new method similar to print_code()
