#33Bogus error message in testMapSumFromZero
33 testMapSumFromZero (see examples/map.sfl) In testMapSumFromZero n, with n = [1,2], opening the sumFromZero node displays bogus error messages as though it is a call to sumFromZero with n = [1,2]. In fact, the node has no input, so there is no call to sumFromZero until we get into map. The problem doesn't occur with recursive functions. It must be because the node has an inlet that expects n, and finds n in the enclosing environment although it is not called.
