FizzBuzz in CUE

This FizzBuzz implementations in CUE, a simple example of a standard program written in a logic structural paradigm.

In a few lines, we can elaborate on many CUE core concepts, e.g. emit values, hidden fields, if-then-else, comprehensions, embedding, lists, ...

We can execute our program in the CLI with

cue def fizzbuzz.cue | cat - <(echo '#max: 21') | cue export - --out=text

The cat - <(echo '#max: 21') part adds to fizzbuzz.cue a refinement of the #max value, thus taking precedence on the default in the file. It is equivalent to having set some input parameters values to our CUE script.
