Comment(by Jeffrey Hellrung <jhellrung@…>):

 Re copy: Sounds good, although I'd have to familiarize myself with the
 boost quickbook (?) documentation creator thingy.  Any helpful
 suggestions?

 The problem your suggestion is it's backwards from what I want:

 copy(transform(src, project()), dest)  <=>  dest[i] = src[i].member_var

 whereas I'm aiming toward

 copy(src, transform(dest, project()))  <=>  dest[i].member_var = src[i]
