Hola,

Since I see you got a programming background, but you are *just* new
to ruby, I'd suggest you should read some code from guys with IMHO
*very* good ruby coding style. (not mine *g*)

Try to read code from a random advanced ruby library, 
most of your questions about API-Design will be answered!

You can start with one of my favorite libraries: datamapper

https://github.com/datamapper/dm-core

I did not got the point in your code so I cannot help you without a
better description about what you are trying to do ;)
