I'm way behind already but here's my #AdventOfCode day 2. I started with day 1 in #Retro but it just seems... underpowered, and underdocumented, and loves to simply crash or drop into the REPL with no error message when anything goes wrong, like a stack underflow, which I do all the time. So I switched back to #Factor, which certainly has no lack of batteries included! Note: my Factor code is *terrible*. (Got them gold stars tho.)
