  So, if I was allowed to interfere, I would suggest that the names should
be named \tex/foo_bar:<argspec>, with "_" a word separator and "/" a module
separator. This way the L3PL team can forget about higher module
abstractions for now, but on the same time ensuring that the L3PL does not
block that the modules concept being introduced fully at some later point.

  If "/" does not prove to be suitable, then it can easily be changed to
something else at some later point.
