08:07 PM Ruby Feature #14788 (Open): `Hash#keys` Could Accept a Block

Sometimes I only need to fetch *some* of the keys from a Hash. With the current `Hash#keys` implementation, this requires fetching all the keys and then selecting the ones I'm interested in. It would be nice if `Has#keys` accepted a bloc... rringler (Ryan Ringler)

Hash#fetch is not mutative. This proposal is for a whiny version of #delete.

hsh = { a: 'a' }; hsh.delete!(:a); hsh # => {}
hsh = { a: 'a' }; hsh.dele... rringler (Ryan Ringler)

I'm as guilty of it as anyone, but as I understand [`!` does not mean destructive](https://www.ruby-forum.com/topic/176830#773... rringler (Ryan Ringler)

06:52 PM Ruby Feature #14546 (Assigned): Hash#delete!

Hash#delete currently returns nil if a given key is not found in the hash. It would be nice to have a way to check that the key was present in the hash. This can be accomplished with with a block, but it would be nice to have some sugar ... rringler (Ryan Ringler)

03:42 AM Ruby Feature #12786: String#casecmp?

Thank you for incorporating this!
I see the changeset implements the new method by calling `String#downcase` on both strings and compares the results for equality. While this does allow unicode support in advance of `String#casecmp`,... rringler (Ryan Ringler)

I agree, and feel strongly that the logic to support those options should live there. Someone smarter than I should probably make the changes Martin... rringler (Ryan Ringler)

The attached patch implements `#casecmp?` by calling `#casecmp` and checking whether the return value is zero. I think this p... rringler (Ryan Ringler)

08:35 AM Ruby Feature #12786: String#casecmp?

Some thoughts on method naming...
* New method: `#casecmp?`
* **PROS:** Nice symmetry with `Fixnum`'s `#<=>` & `#equal?` methods. 'casecmp' seems to imply case-insensitivity (see `String#casecmp` or C's `strcasecmp`)
* **CONS:**... rringler (Ryan Ringler)

Yep. All it would do is check if the return value of `#casecmp` is equal to zero. I'm sure there are plenty of clever uses for `#casecmp`, but I've only ... rringler (Ryan Ringler)
