That difference is significant too, but I'm specifically talking about the difference between trying to make something difficult and neglecting to make it easy. I pick a tool in the first place because it lets me do things more easily.
...Oh, I misquoted it. XD Yeah, thanks for catching that.
Another thing I missed was finishing the efficiency sentence. I was going to devote another paragraph to criticizing the efficiency-should-only-arise-naturally rule for being hypocritical--that an eye to efficiency influences and probably compromises other aspects of the design from the outset--but I determined I actually agree with that rule for Kernel. I think efficiency of fexprs is one of the most significant things Kernel stands to prove, so I don't mind an explicit and upfront goal of efficiency, but efficiency isn't in itself a goal motivating Kernel (I think), so it's good for the rule to be nuanced a bit. (Had I completed the sentence, it would have covered some part of that, but I'm not sure which. XD )
