Hi Joseph and others,

Thanks for tracking this down.
I've made the temporary fix as you suggested.

I've been doing all my testing with \usepackage{expl3} rather than  
loading the modules individually. I've been meaning to stop doing  
this; I've now translated the small amount of code in regression-test  
that was written in expl3 to plain ol' LaTeX so that module loading  
itself can be tested by the files in the test suite. (The already- 
written tests just need a couple of tweaks so the regression results  
don't need to be changed.)

This brings up the question: is there any reason for us to keep the  
modules logically separate? An easy fix might be to add  
\RequirePackage{expl3} to the top of each l3module.

Regarding the best way to fix this particular problem with l3tlp, an  
alternative is to move
   \use_none_delimit_by_q_recursion_stop:w
into l3basics, where are also defined "\use_none_delimit_by_q_nil:w"   
and so on.

Any thoughts?

Will
