Wow. Never knew that! Would it follow from this question that the particular
eye of the particular needle makes a difference on the relative difficulty
of a Tau to Pearson conversion? (That is it might be harder than getting a
camel through the narrow gate but still easier than getting a camel through
an eye of a real needle?)
