The code fragments (usage) I've saw are not thus attractive.

Code should looks simpler, more 'natural'.

This is an important project, but should be setup collaborative.

So, if you setup a ruby-forge project, people can contribute.

call it "attributes" or "attrib" or "has" - but not "traits".

again: no need to research.

I dislike all this, but cannot clarify why.

concept, ruby, flexibility
