Is it possible to provide `Monoid` instances? The presence of `toList` and `fromLists` suggests there is at least *a* implementation, but there is presumably something more efficient.

Panettone is currently not powerful enough to infer and generate the type information for array items, and probably more advanced OpenAPI use cases (read: very nested structures).
Therefore when an…

There should be a `ResamplingBuffer` that collects the incoming data, which has to be a monoid, via `mappend`.

`foldf` is redundant with `reduce`, and `fold*` generally provides the same functionality like `reduce*`, so we should think of better names, e.g.,
- `reduce(R type, init R, f (R,T) -> R | abort R…

Many functions now allow a Scalar argument in addition to the existing `GrB_Function_` functions that exist today. Several are missing though, including Monoid. These would be nice to have, and simpli…
