Project's home: https://www.hexstreamsoft.com/libraries/bubble-operator-upwards/ bubble-operator-upwards is a function that "bubbles an operator upwards" in a form, demultiplexing all alternative branches by way of cartesian product. This operation is notably useful for easy implementation of certain kinds of shorthand notations in macros. A cartesian-product function is also exported, as it's inherently needed to implement the main function. This library is in the Public Domain. See the UNLICENSE file for details.
