    Once again revert argument capturing by local 'go' function.
    
    At last I found an example, where capturing the argument in local 'go'
    function in 'member' causes increased heap-allocation. It is caused by
    'go' function floating out of 'member' and allocating a dictionary and
    the key argument.
    
    This happens only with Map and Set methods. Therefore in IntMap and IntSet,
    'go' function still captures the argument (and GHC shows no increased
    heap-allocation as a result of that).
