	normalization for `Float` is still needed.

Make Enumerartor.product return nil when called with a block

2022-12-21T10:13:15+00:00

Make product consistently yield an array of N elements instead of N arguments

2022-12-21T09:19:19+00:00

Inconsistency pointed out by @mame:

```
>> Enumerator.product([1], [2], [3]).to_a
=> [[1, 2, 3]]
>> Enumerator.product([1], [2]).to_a
=> [[1, 2]]
>> Enumerator.product([1]).to_a
=> [1]
>> Enumerator.product().to_a
=> [nil]
```

Got fixed as follows:

```
>> Enumerator.product([1], [2], [3]).to_a
=> [[1, 2, 3]]
>> Enumerator.product([1], [2]).to_a
=> [[1, 2]]
>> Enumerator.product([1]).to_a
=> [[1]]
>> Enumerator.product().to_a
=> [[]]
```

This was due to the nature of the N-argument funcall in Ruby.

Reject keyword arguments given to Enumerator::Product.new

2022-12-16T04:32:13+00:00

The use of keyword arguments should be reserved for future extension.

Implement Enumerator::Product and Enumerator.product [Feature #18685]

2022-07-30T11:05:14+00:00

Use capture_output instead of capture_io

2021-09-13T12:14:42+00:00

Undef Enumerator::Chain#{feed,next,next_values,peek,peek_values}

2021-03-06T21:56:16+00:00

Previously these methods were defined but raised TypeError, which
seems worse.

Make Enumerator#{+,chain} create lazy chain if any included enumerator is lazy

2021-03-06T21:56:16+00:00

Implements [Feature #17347]

Fix calling enumerator methods such as with_index on Enumerator::Chain

2021-03-06T21:56:16+00:00

This previously raised a TypeError.  Wrap the Enumerator::Chain in
an Enumerator to work around the problem.

Fixes [Bug #17216]
