Thank you @araq. FYI the module did use the experiemental pragma but importing
and using the module requires sprinkling other modules with `{.experimental:
"views".}` or enable `--experimental:views` globally so I switched to detecting
if views were enabled globally when importing the module. I think I will stick
to what I have now, or turn it into `{.error ... }` instead of `{.fatal ... }`,
because I prefer providing a clear message to the user upon import: "if you
want to use this module you must enable enable views".
