Agents are fairly good even at languages designed to trick them. I built one[1] and it does make for a good benchmark[2] to see which LLMs are actually good. I think that a language which is largely similar to others will be a piece of cake for most and any advantage that an existing language will have will be minor enough to not matter.

Btw if folks have ideas of how to make Killswitch even harder for LLMs I’d appreciate them.
