-## 2025-05-15 - Regex Alternation Performance
-**Learning:** Replacing multiple `re.search()` calls for simple literals with a single `re.compile(r'literal1|literal2|...')` regex was ~50% SLOWER in Python.
-**Insight:** Python's `re` module likely uses optimized string search algorithms (like Boyer-Moore) for simple literal patterns, which are faster than the state machine overhead of a large alternation regex.
-**Action:** Prefer multiple simple `re.search()` calls over complex alternations when patterns are mostly literals. Only use combined regex when tokenization/parsing requires strictly ordered matching or when patterns share complex prefixes.

-## 2025-05-20 - Pre-compiling Regex in Loops
-**Learning:** `re.findall(pattern, string)` recompiles (or retrieves from cache) the pattern on every call. In high-frequency functions called inside loops (like complexity estimation), this overhead adds up.
-**Action:** Always pre-compile regexes (`re.compile`) into module-level or class-level constants if they are used repeatedly, especially in tight loops or recursive functions.
+## 2024-05-18 - [Optimized Asyncio Event Loop Handling]
+**Learning:** `asyncio.as_completed()` yields coroutines. Calling `loop.run_until_complete(coro)` for each yielded coroutine inside a synchronous for-loop is a major anti-pattern. It repeatedly blocks the main thread, stops the event loop, and restarts it for every single task, completely defeating concurrency.
+**Action:** Always wrap concurrent task aggregation in a single overarching async function (e.g., `async def run_all()`) where you `await` the individual tasks, and call `loop.run_until_complete(run_all())` exactly once to keep the event loop running smoothly.
