Ruby Numbers and the Memory: how I got confused

Neat! I particularly like how you walk us along with your investigation; I didn't know about `memsize_of`.

Reminds of an "issue" I ran into a while, where Timecop doesn't affect file timestamps, because those are pulled from the OS rather than Ruby.

Are you interested in how Ruby stores numbers in memory? It can look not very sensible initially, but knowing this can help you grow professionally.
