Note that, in Haskell, function application has higher priority then any other infix operation. So, importFile ed = readfile >=> fromRawFile >=> setEditor ed is the same as importFile ed = readfile >=> fromRawFile >=> (setEditor ed) If you write importFile = readfile >=> fromRawFile >=> setEditor then this is (via eta expansion) more or less equivalent to importFile ed = (readfile >=> fromRawFile >=> setEditor) ed which is clearly not the same as the original definition.
