Mojo::ByteStream - ByteStream

=head1 SYNOPSIS

  # Manipulate bytestreams
  use Mojo::ByteStream;
  my $stream = Mojo::ByteStream->new('foo_bar_baz');
  say $stream->camelize;

  # Chain methods
  my $stream = Mojo::ByteStream->new('foo bar baz')->quote;
  $stream = $stream->unquote->encode('UTF-8')->b64_encode('');
  say $stream;

  # Use the alternative constructor
  use Mojo::ByteStream 'b';
  my $stream = b('foobarbaz')->html_escape;
