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 needed to implement the main function.

See the project's home for all details.
