Indeed, makes sense and appear to work here. Please investigate this
solution and test it, if it works, there is no need to involve
__enable_if. Remember to add a big comment in moveable.h encouraging
someone else to pursue option 1 ;)

(indeed, in my mind I was considering the very same kinds of options).

P.S. Now I see that the work in your last patch is not directly affected
by this issue and I can continue my final testing: everything is going
well, for now.
