Following up on some of Proto's review feedback ... Markus Werle wrote:
OTOH: Transforms leave me with mixed feelings. I am not very good at catching ideas without good step-by-step documentation and I got messed up with grammars vs. transforms. This part of proto is new and it looks like a candidate for rework. I'd like to have an extra review in half a year only on the grammar and transform part of proto (*)[comment below]. That's a DSEL all by itself and I guess that interface may have some pitfalls. Larry Evans has worked that out in detail.
I have been working on improving the documentation for Proto's transforms. I hope that the following is a gentler introduction. I would appreciate any feedback about it. http://tinyurl.com/5hg6ke <http://boost-sandbox.sourceforge.net/libs/proto/doc/html/boost_proto/users_guide/expression_transformation.html> As with the rest of Proto's docs, it remains a work in progress.
