The first problem is that mixing prefix and postfix function application within the same line makes it harder to read. When you read code to try to understand what it does, the direction you like to go in is "here's some object, first do this to it, then do that to it, then do this other thing to it, then this fourth thing to produce the final result". In Haskell code with prefix application, this is easy: you read it from right to left. In OO-style code using dots, it's even easier: you read it from left to right. But if you mix the two, it's much harder than either: you first have to figure out where the sentence even begins, which is going to be somewhere in the middle, and then every time the expression switches between prefix and postfix, you have to figure out where to continue reading. The algorithm your brain needs to follow is a lot branchier, so to speak.
It's just as easy as reading function pointers in C :) -- Live well, ~wren
