=head3 Implemeting your own native Lisp functions

.TBC.

=head3 This lisp implementation

=head4 Atoms

 * Reader forms

   * Symbols :

	foo, foo#bar

   * Literals

   * Strings :

	"foo", "\"foo\tbar\n\""

   * Numbers :

	1, -2, 2.5

   * Booleans :

	true, false . Or from Perl: Language::LispPerl->true() and Language::LispPerl->false()

   * Nil :

        nil . Or from Perl: Language::LispPerl->nil();

   * Keywords :

	:foo

 * Lists :

	(foo bar)

 * Vectors :

	[foo bar]

 * Maps :

	{:key1 value1 :key2 value2 "key3" value3}


=head4 Macro charaters

 * Quote ('). :

	'(foo bar)

 * Comment (;) :

	; comment

 *  Dispatch (#) :

   * Accessor (:) :

	#:0 ; index accessor
	#:"key" ; key accessor
	#::key  ; key accessor

   * Sender (!) :

	#!"foo"

   * XML ([) :

	#[body ^{:attr "value"}]

 * Metadata (^) :

	^{:key value}

 * Syntax-quote (`) :

	`(foo bar)

 * Unquote (~) :

	`(foo ~bar)

 * Unquote-slicing (~@) :

	`(foo ~@bar)

=head4 Builtin  lisp Functions

 * list :

	(list 'a 'b 'c) ;=> '(a b c)

 * car :

	(car '(a b c))  ;=> 'a

 * cdr :

	(cdr '(a b c))  ;=> '(b c)

 * cons :

	(cons 'a '(b c)) ;=> '(a b c)

 * key accessor :
