Good point. Though a good side effect is that when you see it used that way you "a-ha!", or you figure it yourself you feel smart. Something like "endoMonoid" d

Good point. Though a good side effect is that when you see it used that way you "a-ha!", or you figure it yourself you feel smart. Something like "endoMonoid" doesn't immediately suggest these use cases either (unless you're a math buff) but if you get to the explanation you're just left with the feeling that this is what was intended all along, not a neat breakthrough. That's reverse API psychology for you :D
