/**
 * Type guards for Apache Arrow types that work across different instances
 * of the Arrow library. These functions use Symbol.for() based markers
 * to identify Arrow types, making them reliable when multiple versions
 * or instances of the library are loaded.
 * 
 * @example
 * ```ts
 * import { isArrowSchema, isArrowTable } from 'apache-arrow';
 * 
 * // Works even with different Arrow library instances
 * if (isArrowSchema(maybeSchema)) {
 *     console.log('This is a Schema from any Arrow version');
 * }
 * 
 * if (isArrowTable(maybeTable)) {
 *     console.log('This is a Table from any Arrow version');
 * }
 * ```
