This is the approach taken by Common Lisp.  Often just a few type
declarations, added to code in inner loops, results in vastly faster code.
Also, although I don't tend to use type declarations while interactively
developing code, I often add them later.  Mostly, I add them to document the
code, but the added safety and faster execution time are nice benefits.
