Subject: [Boost-build] return of check-target-builds rule

If the rule check-target-builds is called as:

   local ctbres = [ check-target-builds some_metatarget some_message : 
some_true_property : some_false_property ] ;

and, let's say, 'some_metatarget' builds, the value of 'cbtres' is not 
'some_true_property'. Instead the value of 'cbtres; is something like:

   <conditional>@object(check-target-builds-worker)@2270.check

Therefore is there a way to subsequently test 'cbtres' to see which 
value was actually chosen, whether 'some_true_property' or 
'some_false_property' in my example, from the return value of the rule ?
