Okay, I'd suggest all in \toks_ (remembering that we'll need to pick up
the primitives not the LaTeX2e versions for l3in2e). I guess we will
need to do the same as LaTeX2e for the initex version of expl3, and
remove direct access to the primitives in user space?

I was imagining that this (being one of those engine-dependent things)
was "for later".
