As a special case, map(None, X) is changed into list(X). (This is necessary because the semantics are changed in this case -- the new map(None, X) is equivalent to [(x,) for x in X].) We avoid the transformation (except for the special case mentioned above) if the map() call is directly contained in iter(<>), list(<>), tuple(<>), sorted(<>), ...join(<>), or for V in <>:. NOTE: This is still not correct if the original code was depending on map(F, X, Y, ...) to go on until the longest argument is exhausted, substituting None for missing values -- like zip(), it now stops as soon as the shortest argument is exhausted. � )�token)� fixer_base)�Name�ArgList�Call�ListComp�in_special_context)�python_symbols)�Nodec � � e Zd ZdZdZdZd� ZdS )�FixMapTaL map_none=power< 'map' trailer< '(' arglist< 'None' ',' arg=any [','] > ')' > [extra_trailers=trailer*] > | map_lambda=power< 'map' trailer< '(' arglist< lambdef< 'lambda' (fp=NAME | vfpdef< '(' fp=NAME ')'> ) ':' xp=any > ',' it=any > ')' > [extra_trailers=trailer*] > | power< 'map' args=trailer< '(' [any] ')' > [extra_trailers=trailer*] > zfuture_builtins.mapc �N � | � |� � rd S g }d|v r2|d D ])}|� |� � � � � �*|j j t j k rQ| � |d� � |� � � }d|_ t t d� � |g� � }�n�d|v r{t |d � � � |d � � � |d � � � � � }t t j |g|z d� � � }�n_d |v r"|d � � � }d|_ n�d|v r�|d }|j t j k r�|j d j t j k rd|j d j d j t"
