Go select vs Rust select! fairness and determinism
This tests runtime fairness in concurrent primitives. Contrast Go's pseudo-random case selection with Tokio's randomized default and its opt-in biased; top-down mode. Red flag: claiming Go uses source order or that Rust randomization is unavoidable.
This tests runtime fairness in language runtimes versus async executors. Explain that Go's select pseudo-randomly picks among ready channels to prevent starvation, so case order does not matter. Then note Tokio's select! randomizes by default too for fairness, but uniquely offers a biased; mode to poll branches top-down for deterministic behavior and lower RNG cost. Red flags are claiming Go uses strict declaration order or that Rust select! is always deterministic.
