  Well, assuming the code below is correct, it doesn't seem to make any
difference:

    for meth in Queue.constructors():
        meth.exclude()

 But, anyway, I just white-listed the pure virtual methods and now it
compiles.  They won't work in runtime because they handle unregistered
parameters, but that is a lesser evil.

  Thanks anyway,
