In v0 and v1, one could make a pulse former using a trick with a few NOT gates, an XOR, and an SR-Latch. I think this was an emergent "feature" due to the way that the simulation was originally written (there was effectively a gate delay on the NOT gate).
It looks like the rewrite of the simulation made that not a thing anymore, so I'm wondering if there's still a way to make a single-pulse type thing that has a pulse that is faster than the built-in clock?
