Though in some cases the performance impact could be significant, my concern is readability. My understanding of the concept of partial function application is that it's about supplying some but not all of the arguments. So when I see `partial` in code, I expect more arguments to be supplied later, which is confusing when that's not the case. (Obviously context can make it easy to see that there will be no more arguments, but often that context is not present.)
