This is just a compilation of all some frequent includes I do on my ruby code

Hash

deep_merge

When merging Hashes it will take care of merging nested hashes

deep_has_key?

Provide multiple keys and it will tell you if they are contained in the current hash, taking nesting into account

deep_value

Finds a value taking nesting into account

select_keys

Receive a list of keys and return a hash subset containing the keys specified

Fixnum

sign

Returns 1 or -1 matching the sign of the current fixnum

Array

---

all_equal?

Return true if all the items of the array are equal Note: an empty array will solve to true while i'm unsure it's desired behavior
