 * Compiles an Elo expression to a callable JavaScript function.
 *
 * Every Elo expression compiles to a function that takes `_` (the implicit input) as parameter.
 * You call the returned function with your input value.
 *
 * @example
 * ```typescript
 * import { compile } from '@contextvm/elo';
 * import { DateTime, Duration } from 'luxon';
 *
 * // Simple expression using _ (implicit input)
 * const addTen = compile<(x: number) => number>(
 *   '_ + 10',
 *   { runtime: { DateTime, Duration } }
 * );
 * addTen(5); // => 15
 *
 * // Temporal expression
 * const inThisWeek = compile<(d: unknown) => boolean>(
 *   '_ in SOW ... EOW',
 *   { runtime: { DateTime, Duration } }
 * );
 * inThisWeek(DateTime.now()); // => true or false
 * ```
