A 2000-operand (bit-and (let …) …) takes 32 s to check (37 s before the bit operators);
2000 plain names take 0.03 s. Something per operand is quadratic or worse.

Under --dev each temp allocation (i64->bytes, dyn text crossing into str) costs about

slowest ten, and group tests under per-module aliases so a lane runs only its own.
