I tried to optimize my code in preparation from part two but of course as it turns out that still wasn't fast enough.

Nice. Thought I wasn’t going to see any other bit twiddling day 12s here today :smiley:

You can do 4 fewer gets from the prev generation per cell: shift the pattern left by 1, or it with the next bit mask only the low 5 bits.

Oh I misinterpreted it. I thought pattern was an `Int`, and you were using it as an index into rules

Yeah I could fake it a bit faster still, but turns out that's not necessary!
