Thanks.  On the mend, but it takes time...

No opinion on this myself, but aliases have a cost in terms of 
confusion (what's the difference?   err there is none) whereas 
there may be some value in reimplementation with appropriate 
semantics at some future point.

But I think the closest sticking point is not lack of order in 
library organisation - just that the documents are written from 
the perspective of the library writer and there is currently no 
coherent, complete, and polished set of documents primarily 
oriented to 'how do I accomplish this task'. I understand why 
that is, but if one identifies a problem one can work away at it 
slowly over time.
