If you do functional programming (like in Wolfram Language) you've probably used lots of pure functions, or lambdas.  But what are lambdas like in the wild?  Things I'm doing in CS, bio and ML converged to make me curious to find out...  And as seems to happen whenever I go exploring in the computational universe ... they surprised me ...
