Thanks — and no worries, that’s a great question!

Right now, PyXL runs fully in-order with no speculative execution. This is intentional for a couple of reasons: First, determinism is really important for real-time and embedded systems — avoiding speculative behavior makes timing predictable and eliminates a whole class of side-channel vulnerabilities. Second, PyXL is still at an early stage — the focus right now is on building a clean, efficient architecture that makes sense structurally, without adding complex optimizations like speculation just for the sake of performance.

In the future, if there's a clear real-world need, limited forms of prediction could be considered — but always very carefully to avoid breaking predictability or simplicity.
