by the way, why is this still saying LaTeX3 error? I thought we agreed 
on something like something like

   ! LaTeX cmd Error: Required argument missing for \foo.

not sure what the "type/module" should be, but I think it should stay 
being "LaTeX XXX Error:" or perhaps for kernel errors just "LaTeX 
Error:" or "L3 programming layer Error:" but that probably takes out too 
much out of the few chars available in an expandable message
