Okay fair it’s more than 50 lines, I guess my definition of non-trivial is something you can’t quickly think of a design for. I’ll try it later and see if there’s some gotchas I can’t think of :)

I had the same initial reaction as the other person. Should be easy right? I think you’re right though, there are probably many more steps to getting this right than it seems on the surface.

I kind of want to take your 50 line challenge however :) I always loved playing poker, might be a fun exercise.
