# I18n translation metadata is useful when you want to access information
|

|

# about how a translation was looked up, pluralized or interpolated in
|
||
|
|
# your application.

# msg = I18n.t(:message, :default => 'Hi!', :scope => :foo)

# msg.translation_metadata

||
|
|
# # => { :key => :message, :scope => :foo, :default => 'Hi!' }
|

# If a :count option was passed to #translate it will be set to the metadata.

# I18n::Backend::Simple.include(I18n::Backend::Metadata)
