        streams => [ \*STDIN, "/path/to/file.yaml" ],
        on_doc => sub {
            my ( $self, $doc, $eof ) = @_;
            # ... do something with $doc
        },
        on_child_eof => sub {
            my ( $self ) = @_;
            say STDERR "Switching stream";
        },
        on_read_eof => sub {
            my ( $self ) = @_;
            # All streams have been exhausted
            $self->loop->stop;
        },

    $loop->run;

DESCRIPTION

This module reads a series of input streams in the default format (determined by "get_default" in ETL::Yertl::Format). Input streams can be filehandles (like STDIN) or paths to files.
