Isn't that just terrible? I hate the fact that Haskell was defined to neither trap the overflow
or just treat everything as Integer [like Scheme]. A sacrifice of program safety in the name
of efficiency.

I disagree with this choice and posit that a clever implementation can minimize the cost
of the overflow checking in most relevant cases.

I wish this fatal flaw would be reconsidered for the next major revision.
