On-chain face (@all!)

Return true if every element satisfies a named boolean callback, stopping at the first failure. Empty arrays return true. Callbacks support composed helpers and ABI calls over typed single-word or multiword elements.

A predicate that compares one call over the element with a value, such as a balance against a minimum, costs one call per element. The value may be a call of its own: it is read once, not once per element.
