import { Iterator as Iter, IterableIterator } from '@stdlib/types/iter';
// Define a union type representing both iterable and non-iterable iterators:
type Iterator = Iter | IterableIterator;
/**
* Returns an iterator which iteratively evaluates the natural logarithm of the beta function.
*
* ## Notes
*
* - If provided a numeric value as an iterator argument, the value is broadcast as an **infinite** iterator which **always** returns the provided value.
* - If an iterated value is non-numeric (including `NaN`), the returned iterator returns `NaN`. If non-numeric iterated values are possible, you are advised to provide an iterator which type checks and handles non-numeric values accordingly.
* - The length of the returned iterator is equal to the length of the shortest provided iterator. In other words, the returned iterator ends once **one** of the provided iterators ends.
* - If an environment supports `Symbol.iterator` and all provided iterators are iterable, the returned iterator is iterable.
*
* @param x - input iterator
* @param y - input iterator
* @returns iterator
*
* @example
* var uniform = require( `@stdlib/random/iter/uniform` );
*
* var iter = iterBetaln( uniform( 0.0, 2.0 ), uniform( 0.0, 2.0 ) );
*
* var r = iter.next().value;
* // returns <number>
*
* r = iter.next().value;
* // returns <number>
*
* r = iter.next().value;
* // returns <number>
*
* // ...
