Yikes!  What's with the snarkiness guys?

One thing you should consider in particular, Alexis, is the
performance impact Ruby's objects are causing.  In your C++ code, it
appears that everything's running on the stack.  The Ruby interpreter
is allocating and disposing of every object in the Ruby code onto the
heap and running garbage collection on them.

It might be worth attempting to at least change the code into
accepting Sodoku puzzles of any size (bear in mind I haven't looked at
Sodoku solvers very much myself, so this may have all sorts of
technical challenges I'm unaware of).
