Do we still need the explicit keyword? Won't the private_access_tag_t prevent the compiler from using implicit type conversion?

Not if the parameter pack is empty, which it likely never will be in practice, but explicit doesn't hurt.

hmm, that's crazy, i didn't know that! that pulls the rug under the purpose of having the private tag :)

There's no real motivation to allow implicit construction as it is only constructed in one file, and even that is handled by a macro.

Rebased to develop. |
Apply a minor cleanup in `TypedField`: * Remove a non-working and unused move constructor. * Constrain the remaining constructor to not be overly generic enough as to be used as a copy or move constructor.
