Wow. I like the (sqrt -1). I did not realize CL will actually give you a complex #C(0.0 1.0) (!). Along those lines, a negative modulus can be tricky, though

Wow. I like the (sqrt -1). I did not realize CL will actually give you a complex #C(0.0 1.0) (!). Along those lines, a negative modulus can be tricky, though I can't remember which language(s) get it wrong. Perhaps not wrong, but different. -7 % -2 is usually -1. Seems like exactly the kind of thing I'd want to find in the table. Maybe it's all consistent now? Rosetta linked by fiatjaf is great to see larger structure, Python vs Clojure type stuff.
