@petergaultney this is very much experimental and a work-in-progress at this point ;)

Is there an issue, or anything, describing what's going on?

From a quick glance, this seems to be the new feature:

    hook = customize(
        c,
        Small,
        V((fs := f(Small)).a).ensure(greater_than(10)),
        V(fs.b).ensure(len_between(0, 10)),
    )

I'm pretty clueless as to what's going on, but may I suggest also supporting something like:

    hook = customize(
        c,
        Small,
        V((fs := f(Small)).a) > 10 and
        0 <= len(V(fs.b)) < 10,
    )

By overwriting the __gt__, __len__, __and__, and such operators, to construct these validations in a more fluent way?

This would be similar to how libs like SQLAlchemy handle some queries.

These operators could return the same that .ensure(greater_than(10)) would return, for example, and not bool.
