We only have cumsum and cumprod right now, and it would be nice to have the ! variants as well.

If we do that, can we also have cummax!, cummin! and cumsum_kbn?

It would be nice to have general purpose scans so that we can have scans with user defined functions as well.

Scanning and inplace scanning are recently added to NumericExtensions.jl (see http://lindahua.github.io/NumericExtensions.jl/scan.html)

These may be migrated to base together with some other parts of the package.
