[scala] update on visiting algebras

[Meredith Gregory]

Scalads and Lasses,

i just found Neil Mitchell's excellent paper on Uniplate - an update to SYB (scrap your boilerplate). It would appear he was thinking along the lines i was that a traversal pattern ought to enable both serialization (or dually, query) and reduction (rewrite to a normal form). His analysis is much more complete than mine, but the type requirements on the underlying traversal mechanism appear to remain the same as i found.

Best wishes,

--greg
