Not to start a flame war or religious debate, but I don't think that eta-expansions should be considered bad style. I realize that composition-style is good for certain types of reasoning, but fully eta-expanded code has an important legibility advantage: you can tell the shape of its type just by looking at it! Personally, I'd rather read the original version.
