I admit that I am slow to come up with
new ideas. 'Alien fairy dust' is the only
thing I can imagine that would have
produced the scenario you (and
standard PA) propose.
However, I am sure that the bubbling
ferment of lively discussion and bright
ideas that represents modern PA is full
of possible solutions to this problem.
Would you mind sharing your extensive
knowledge? Please list the top two or
three ideas -- in your opinion.
