AFAIK people used `setq` before `setopt`. For vars that come with
setter functions, this usually doesn't work quite the same, but in 99%
it's good enough if the `setq` is performed early during startup.
You can also
(put '<SYM> 'custom-type t)
if you want to disable type-checking for a specific variable.
