already have mastered the skill of leveraged reading: getting what you can out
of an article you don't fully understand, so that you can discuss it with the rest of
the group and hopefully get to a point where you can read it again and
-get more out of out. (Rinse and repeat.)

+<!-- Haskell Curry had ideas that he felt were validated upon reading a 1924 paper by M. Schönfinkel "Uber die Bausteine der mathematischen Logik" which used combinators in a similar way to his own ideas. Haskell then wrote "An analysis of logical substitution" which appeared in the American Journal of Mathematics in 1929. -->
