I can see from this exchange that, while the underlying 
concepts are very simple, the way the material is presented 
to people causes confusion. Olin obviously has a very 
thorough grasp of what does what and of how it can and 
should and shouldn't be used.

So - I have no doubt that this is all spelt out in 
documentation, but it's easy for beginners to be confused by 
such. Is there a reference available that spells this out 
clearly enough that a studious beginner can understand it 
well and get it right? The corrections and directions from 
Olin that are scattered through the recent posts look like 
an excellent start to such a guide if it doesn't already 
exist.
