    W: Write, 

Writes a keyword to the specified writer.

fn begin_list<W: ?Sized>(&mut self, writer: &mut W) -> Result<()> where
    W: Write, 

Called before any list elements. Writes a ( to the specified writer.

fn begin_list_element<W: ?Sized>(
    &mut self,
    writer: &mut W,
    first: bool
) -> Result<()> where
    W: Write, 

Called before starting to write a list element. Writes a space if needed to the specified writer.

fn end_list_element<W: ?Sized>(&mut self, _writer: &mut W) -> Result<()> where
    W: Write,

    W: Write, 

Called after all list elements have been written. Writes a ) to the specified writer.

fn write_dot<W: ?Sized>(&mut self, writer: &mut W) -> Result<()> where
    W: Write, 

Called before writing the tail of an improper list, or more generally, the cdr field of a cons cell. Writes a . to the specified writer.
