Demonstration of possible reductions in library size

[mtrimpe]

I was playing around and noticed some repetition in the code, so I thought I'd cook up a little example of how you can make some simple micro-DSLs in these cases to reduce library size.

It's getting late now so I'm just sending the pull request even though it's broken, very broken. It still shows what's possible though and achieves a bit of size reduction already.

Good idea. I was looking into making the code simpler and shorter. These are some good suggestions.
