/** |

* Returns an iterator over all supported currencies. |

* |
| 46 |
* Uses yield (Generator) instead of ArrayIterator for better performance and memory efficiency: |
| 47 |
* - Lazy loading: Creates Currency objects only when needed during iteration |
| 48 |
* - Memory efficient: Doesn't load all 100+ Currency objects into memory at once |
| 49 |
* - Dynamic data: Based on give_get_currencies_list() which can change via filters |
| 50 |
* - Better performance: Especially important for large currency lists (100+ currencies) |
| 51 |
* |
| 52 |
* This approach is more suitable than ArrayIterator (used by BitcoinCurrencies/ISOCurrencies) |
| 53 |
* because GiveWP's currency list is dynamic and potentially large, unlike static ISO lists. |
