// (in fact, we can't, as JSII does not work for standalone functions!).
// So, while the functions are exported from this file,
// this file is not listed in index.ts,
// and so these functions are effectively 'module-private'.
// To make it clear that this file should not be exported,
// we place it in a subdirectory of lib called 'private'.
