I18n::Base#handle_exception

Any exceptions thrown in translate will be sent to the @@exception_handler
which can be a Symbol, a Proc or any other Object unless they're forced to
be raised or thrown (MissingTranslation).

If exception_handler is a Symbol then it will simply be sent to I18n as
a method call. A Proc will simply be called. In any other case the
method #call will be called on the exception_handler object.

Examples:

  I18n.exception_handler = :custom_exception_handler              # this is the default
  I18n.custom_exception_handler(exception, locale, key, options)  # will be called like this

  I18n.exception_handler = lambda { |*args| ... }                 # a lambda
  I18n.exception_handler.call(exception, locale, key, options)    # will be called like this

  I18n.exception_handler = I18nExceptionHandler.new               # an object
  I18n.exception_handler.call(exception, locale, key, options)    # will be called like this
