In nix-effects, this trampoline is the evaluation loop for a freer monad interpreter. A computation is a chain of algebraic effects: send "get" null, then send "put" 42, then more effects, possibly thousands deep. A naive recursive interpreter would call itself for each one, building stack proportional to chain length. With the trampoline, each effect is one genericClosure step: the operator calls the handler, which returns a resume value (feed to the continuation, keep going) or an abort value (discard the continuation, halt immediately). Continuations compose via an FTCQueue, a purely functional queue with O(1) snoc and amortized O(1) uncons, which eliminates the left-nesting pathology that makes naive free monads quadratic.
The United Nations Mission in South Sudan (Unmiss) said about 1,000 civilians began seeking protection near its base in the affected area. The mission said it was alarmed by the surge in violence in the region over the past 48 hours.
