David, thanks for this carefully reasoned analysis of TestGL and proposal 
for re-organizing the GL and CP.

All... we have two proposals for re-organizing.  There are certain things 
in common (esp. thoughts about major groupings of old GL & CP) and some 
differences as well (esp. order, and slightly different groupings).  It 
seems to me that we ought to take one proposal as base, and use the other 
proposal to generate any fundamental issues against base.

Given that Mark and Kirill have both generated specific comments against 
the Peter/Patrick proposal, it might be sensible to use that as base.

What do you think (all)?


p.s.  As I read David's proposal, I tried to correlate major groupings to 
Peter/Patrick proposal.  I.e., where in P/P proposal is David's concept 
mostly addressed.  This is quick (and may reflect some misunderstandings of 
the proposals).  Specific comments....
