babel-polyfill-safe

A wrapper around babel-polyfill (v6.6.1) that prevents errors when the polyfill is required multiple times. It checks a global flag to avoid re-applying polyfills, solving the 'only one instance of babel-polyfill is allowed' issue. The package is intended for legacy Babel 6 environments, is no longer actively developed, and users should migrate to @babel/polyfill or direct core-js/regenerator-runtime imports.
