I'm great with that goal really, I just don't think changing Ruby  
semantics is the way to get there.

Here's my new idea.  What about solving this with default values for  
columns?  If speed was defaulting to 0 instead of nil, we wouldn't  
have a problem.  That seems to me to be what these example's intend  
anyway.

Am I crazy?
