I can Port from Python -> Common Lisp at a rate of ~100 LoC per hour, and that's a pretty friendly port (the yield expression is the only thing that can't be just done line-by-line; truthyness is the only real "gotcha" as there are a lot of "false" values in Python, but only 1.5 in Lisp[1]).

1: I say 1.5 because there is only one false value, but it has 2 idiomatic meanings: nil (equivalent to python's None) and the empty list.
