No, ADL can not kick in because the overloads are in namespace
boost::la and the user-defined types they are typically called with
are in other namespaces. You can safely bring boost::la into scope
globally, the overloads this will introduce will not clash with

This is a good idea. I am planning to separate the operator overloads
in a different namespace from everything else, since the operator
overloads are always safe to bring into scope with using, yet ADL
doesn't work for them.

Thanks, I am hoping to get some more feedback, then I think I'll do a
what will probably be a very light refactoring. After that I'll
request a review and we'll see. :)
