[Haskell-beginners] User defined operators : setting precedence

Hello, Can anyone point me to some documentation that describes how one may set precedence in a user defined operators? I have composition operators so that I can write: let ruleSuffixCapsFreq = ruleT |> suffixT .> capitalizeT .> freqT but I seem to be forced to write: let ruleSuffixCapsFreq = ruleT |> (suffixT .> capitalizeT .> freqT) and I would like to avoid this. TIA, Hugo F.
