Documentation
Allows for reverse merging where its the keys in the calling hash that wins over those in the other_hash. This is particularly useful for initializing an incoming option hash with default values:
def setup(options = {}) options.reverse_merge! :size => 25, :velocity => 10 end
The default :size and :velocity is only set if the options passed in doesnât already have those keys set.
