+Style #8
+==============================
+
+Variation of the candy factory style, with the following additional constraints:
+
+- Each function takes an additional parameter, usually the last, which is another function
+- That function parameter is applied at the end of the current function
+- That function parameter is given as input what would be the output of the current function
+- Larger problem is solved as a pipeline of functions, but where the next function to be applied is given as parameter to the current function
+
+Possible names:
+
+- Kick your teammate forward!
+- Continuation-passing style
+- Crochet loop
