ludic/packages/ludic.update/tick.ludic
Orkuncakilkaya 71735b10a2 feat(base): 0.R4 - a queue keeps its own count, so every package verb takes only its own state; ludic migrate state --prune
ludic.base's Queue<T> carries a QueueTag (its name and pending count): queue_new(name), q_push(q, v),
q_drain(q), q_clear(q) take no BaseState, and core_undrained(tags) names the given queues still holding
facts. A reducer on a package's state can now call that package's verbs (wallet_earn(wallet_st, n)).

ludic migrate state --prune (ludicc --migrate-prune) takes out each state parameter a function no
longer uses, nor anything it calls, and the argument that fills it - including an argument for a
parameter the callee has dropped, which is taken out before the call is checked, so a generic's T is
told by the argument that says it. A reducer keeps its state. --dry-run now counts the edits it would
make. Every package was moved with it: 608 base_st parameters and their arguments, 1889 edits.
