8.1 Constraints

Variation of the Pipeline 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.
• The 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.
