It's quite possible I am missing the point -- the set of complicated 
macros you show do not make it easy (for me) to understand what the 
problem is and sadly I do not have any time to devote to deciphering 
them.  Perhaps a natural language description of the property you are 
trying to check would help (me) more than the macros you show.

Anyway, all I wrote in my previous mail was that the pattern of first 
doing a set up action, then running a test that returns some result that 
you save in a variable, then performing a cleanup action and finally 
checking whether the result satisfies or falsifies the property you want 
your test to satisfy is so natural --to me at least-- and general that I 
cannot possibly see why it does not work in what you want to do.  But of 
course what's "natural" is not defined objectively.
