instance method `reverse_merge`

Ruby on Rails 4.1.16

Since v3.0.20

Compare with:

reverse_merge(other_hash)

Merges the caller into other_hash. For example,

options = options.reverse_merge(size: 25, velocity: 10)

is equivalent to

options = { size: 25, velocity: 10 }.merge(options)

This is particularly useful for initializing an options hash with default values.
