I did try to list these aspects in the comparison table at the
beginning of the Alternatives section. Please let me know if it is not
clear enough.

This is captured under "Can be defined within expressions". I can add
the function naming issue.

This is captured under "Bind variables in scope" that for Boost.Lambda
reads "No (but variables in scope are accessible as usual within
expressions)." and for Boost.Phoenix the same plus "Yes (using let
which also allows to bind by constant reference)."

I think this is arguable but I am providing code examples (actually of
simple local functions) so users can judge on their own.

Do you have a reference for this--like a WiKi page. I don't understand
this topic and I'd need to study it more before adding to the docs.
Thanks a lot.
