Essentially the same idea as the one from Brent Yorgey. Works fine till the operations can fill easily on one line. Then it does not scale that well since when it needs to be on more lines it interferes with automatic insertion of curly braces and semicolons by the layout rules (which are influenced by the context). Of course when there are more transformations it makes sense to name the intermediate results differently, but even few transformations may not fit easily when identifier names are long.
I have no idea what you're talking about. It works fine on multiple lines: f x = g . transform displacement . scale factor $ x is perfectly valid. Tastes may vary, you might prefer trailing .s to leading .s, but the idea is the same. Jules
