This series implement two new operations for plugins: - Store inline allows to write a specific value to a scoreboard. - Conditional callback executes a callback only when a given condition is true. The condition is evaluated inline.
It's possible to mix various inline operations (add, store) with conditional callbacks, allowing efficient "trap" based counters. It builds on top of new scoreboard API, introduced in the previous series.
