The section is very informative and explains the concept nicely!

Also a very nice addition to the existing documentation. What's not
immediately clear after reading that section is when proto::as_expr is
called within the library, or when you want to call it as a user. Some
clarification would be good here.

There is a small typo here: "Just how r_i_diculous would it be to copy..."
One addition which might be helpful to the interested reader is to
explicitly say that proto's data "slot" is used for the external transform.

Thanks for adding this documentation!

Hope that helps,
