 * Written in C for high performance
 * Detects and halts arithmetic overflow for correctness
 * Uses native CPU instructions for fast overflow detection
 * Defers GCD calculation until requested or absolutely required
 * Supports btree and hash indices
 * Implements Stern-Brocot trees for finding intermediate points
 * Coercion from integer/bigint/tuple
