Explicit singletons. More manual than singletons, but potentially easier to
use because you can give GHC more explicit information (compared to singletons
which often threads things through the Sing type family and SingI type
class).
Uses phadej’s defun package for defunctionalizing type families. (Edit,
actually doesn’t require defun just yet. But I think that’s just because I
haven’t bothered defunctionalizing things.)
Requires GHC >= 9.6 for the builtin SNat, SSymbol etc. singletons.
