// Generate unique IDs for use as pseudo-private/protected names.
// Similar in concept to
// .
//
// The goals of this function are twofold:
//
// * Provide a way to generate a string guaranteed to be unique when compared
//   to other strings generated by this function.
// * Make the string complex enough that it is highly unlikely to be
//   accidentally duplicated by hand (this is key if you're using `ID`
//   as a private/protected name on an object).
//
// Use:
//
//     var privateName = ID();
//     var o = { 'public': 'foo' };
//     o[privateName] = 'bar';
export function id(): string {
    // Math.random should be unique because of its seeding algorithm.
    // Convert it to base 36 (numbers + letters), and grab the first 9 characters
    // after the decimal.
