Description

Anyway to access information about the source of YAML when defining a type? I have a case where I want to know if the source was a file and what the file path is.

YAML::add_domain_type("foo.com,2011", "foo") do |type, value|
    from_file = ?  # 'foo.yaml'
    Foo.new(value, :file=>from_file)
end

YAML.load(File.new('foo.yaml'))

Research direction

Start with the YAML::add_domain_type callback and YAML.load(File.new(...)) example shown in the issue. Investigate how source metadata is passed through loading and whether the callback can receive a file path. Done means a type definition can reliably distinguish file-backed YAML and access its path, with the behavior covered by tests.
