+/**
+ * Transforms the items of the list with the transducer and appends the
+ * transformed items to the accumulator using an appropriate iterator function
+ * based on the accumulator type.
+ *
+ * The accumulator can be an array, string, object or a transformer. Iterated
+ * items will be appended to arrays and concatenated to strings. Objects will
+ * be merged directly or 2-item arrays will be merged as key, value pairs.
+ *
+ * The accumulator can also be a transformer object that provides a 2-arity
+ * reducing iterator function, step, 0-arity initial value function, init, and
+ * 1-arity result extraction function result. The step function is used as the
+ * iterator function in reduce. The result function is used to convert the
+ * final accumulator into the return type and in most cases is R.identity. The
+ * init function is used to provide the initial accumulator.
+ *
+ * The iteration is performed with [`R.reduce`](#reduce) after initializing the
+ * transducer.
