Yeah, GCL's scoping rules are confusing. Jsonnet got rid of "up" and a few other details and suddenly things are much less likely to blow up in your hands. curiosity: I once wrote a GCL function that computed a PNG data url (the thing that looks like '<img src=data:image/png;base64,iVBORw...' and can be natively opened by your browser) whose content was a rendering of the mandelbrot set. It took several GB of RAM to evaluate. Didn't port it to jsonnet yet...
