code: function isProbablyWebpackModule (node) {
          return isElementOfArray(node) &&
            isArgumentToFunctionCall(node.parent()) &&
            isIIFECall(node.parent().parent())
        }
docs: tries to divine if this function is a webpack module wrapper. returns true iff node is an element of an array literal which is in turn an argument to a function call expression, and that function call expression is an IIFE.
